Rom 12:2
“And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God”.
There’s something you must do to your natural mind, even after you have believed, inorder to fully embrace and consumate the love of God which He gave freely in Christ.

The above verse states just that: ‘you have to renew your mind and permit a complete make-over of how you see God, and by extension, your new self.
The MSG version of the Bible brings this verse out in modern English doing justice to it in terms of better understanding.

Rom 12:1-2(MSG)
“So here’s what I want you to do, God helping you: Take your everyday, ordinary life—your sleeping, eating, going-to-work, and walking-around life—and place it before God as an offering. Embracing what God does for you is the best thing you can do for him. Don’t become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out. Readily recognize what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.”

God’s desires an intimate walk with us and His terms are not taxing.

Jesus said in Matthew 11:30: “For my yoke is easy, and my burden is light”.
If you renew your mind, which is what true repentance is all about, you will indeed enjoy the ride.
God’s terms is not new. Prophet Micah prophesied it centuries before Christ:
Micah 6:6-8
“He hath shewed thee, O man, what is good; and what doth the LORD require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?”
And Jesus endorsed this prophesy as applicable to us under the New.
Matthew 22:37-40
“Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets”.
So we see that God’s wants us to love mercy and He goes his way to supply it. The Bible says that the love of God is shed abroad in our hearts. Rom 5:5 AMP “Such hope in God’s promises never disappoints us, because God’s love has been abundantly poured out within our hearts through the Holy Spirit who was given to us”.
Loving mercy then becomes :i. Our Motivation, ii. Our Source of Power
Jesus said if thou knowest what is meant by I’ll love mercy and not sacrifice…
Matthew 9:13″But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.”
The Lord by this statement completely redefined love as mercy in action. Mercy is the purest motivation of love, and also the strongest demonstration of it. The Parable of the GOOD SAMARITAN (Luke 10:29-37) was to further teach on this:
“Love thy neighbor”
Who is my neighbor ?
The next person you encounter in your daily walk, Jesus says, that’s who is your neighbour. As many as you have to deal with daily, are indeed your neighbours.
The Samaritan is the only one who showed mercy. The Priest couldn’t because of the Law. He would be defiled by touching a dead man according to the Law. His self-interest prevailed over mercy.
The Levite couldn’t because of same reason.
But the Samaritan, bound by no law and  outside the knowledge. In no covenant with God. But he had one thing: THE QUALITY of Mercy. He was the one who shewed love to his neighbour.
And Jesus ended that parable by saying:
vs 37″And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise”.
Where exactly are we to love mercy?
a. The first person to show mercy is to yourself.
Many have held on to their past sins and continue to beat themselves black and blue for it, even after God has forgiven.
In fact, not only has God forgiven, He has forgotten about it and promises to remember them no more.
Hebrews 8:12
“For I will be merciful to their unrighteousness, And their sins and their iniquities will I remember no more”.
In our main text Rom 12:1, it reads;
“I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service”.
How do you read this verse ?This is the litmus test of whether you truly understand Grace?
Eight in ten believers or more will take this as a call to duty. Because they will read the above verse as a charge requiring them to strive to become a sacrifice acceptable to God through a holy living.
Let’s read it again. Go back to the pretext and see what topic the Apostle was discussing. 
In Roman 11, Paul was teaching the amazing mercy of God towards Israel. He wasn’t talking about God’s demand on them for holy living.
Romans11:27-33
“For this is my covenant unto them, When I shall take away their sins. As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers’ sakes. For the gifts and calling of God are without repentance. For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: even so have these also now not believed, that through your mercy they also may obtain mercy. For God hath concluded them all in unbelief, that he might have mercy upon all. O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!”
b. The second place to love mercy is on your your brother or sister in Christ.
Eph 4:32″and be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you”.
Let them go acquitted from your trial court, so you too can be released from all clamour and strive at heart.
Paul said to Philemon; “If he hath wronged thee, or oweth thee ought, put that on mine account;”(Philemon 1:18).
If you can’t forgive easily without charging someone, then put that charge on Christ who died for you and forgave you more.
c. The third place to love mercy is on the sinner, and the one you consider a stranger and outside of God’s family.
Our charge is to become an extension of Christ to the whole world for whom Christ died. (Jn 3:17).
We are not called to condemn the world, or prosecute men for their sins by throwing their errors and bad habits at their faces. We are called to show mercy.Jesus demonstrated time and again that it is only with mercy you win the lost.
Luke 7:37‭-‬48
“And, behold, a woman in the city, which was a sinner, when she knew that Jesus sat at meat in the Pharisee’s house, brought an alabaster box of ointment, and stood at his feet behind him weeping, and began to wash his feet with tears, and did wipe them with the hairs of her head, and kissed his feet, and anointed them with the ointment. Now when the Pharisee which had bidden him saw it, he spake within himself, saying, This man, if he were a prophet, would have known who and what manner of woman this is that toucheth him: for she is a sinner. And Jesus answering said unto him, Simon, I have somewhat to say unto thee. And he saith, Master, say on. There was a certain creditor which had two debtors: the one owed five hundred pence, and the other fifty. And when they had nothing to pay, he frankly forgave them both. Tell me therefore, which of them will love him most? Simon answered and said, I suppose that he, to whom he forgave most. And he said unto him, Thou hast rightly judged. And he turned to the woman, and said unto Simon, Seest thou this woman? I entered into thine house, thou gavest me no water for my feet: but she hath washed my feet with tears, and wiped them with the hairs of her head. Thou gavest me no kiss: but this woman since the time I came in hath not ceased to kiss my feet. My head with oil thou didst not anoint: but this woman hath anointed my feet with ointment. Wherefore I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little. And he said unto her, Thy sins are forgiven”. 

SELAH!
