And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
Romans 12:2, NKJV

The day of your salvation is the beginning of a spectacular journey through which the Lord God "works in you both to will and to do for to His good pleasure" (Philippians 2:13). Let us consider what the Lord has said in His word concerning the behavior of those who profess faith in Christ Jesus.

What Christians Should Do

Your Personal Responsibility (Romans 12)

Present yourself as a Living Sacrifice to God

For this reason I make request to you, brothers, by the mercies of God, that you will give your bodies as a living offering, holy, pleasing to God, which is the worship it is right for you to give him.

And let not your behaviour be like that of this world, but be changed and made new in mind, so that by experience you may have knowledge of the good and pleasing and complete purpose of God. Romans 12:1-2

Serve God with the Spiritual Gifts that He has Given You

But I say to every one of you, through the grace given to me, not to have an over-high opinion of himself, but to have wise thoughts, as God has given to every one a measure of faith.

For, as we have a number of parts in one body, but all the parts have not the same use,

So we, though we are a number of persons, are one body in Christ, and are dependent on one another;

And having different qualities by reason of the grace given to us, such as the quality of a prophet, let it be made use of in relation to the measure of our faith;

Or the position of a Deacon of the church, let a man give himself to it; or he who has the power of teaching, let him make use of it;

He who has the power of comforting, let him do so; he who gives, let him give freely; he who has the power of ruling, let him do it with a serious mind; he who has mercy on others, let it be with joy. Romans 12:3-8

Behave Like a Christian

Let love be without deceit. Be haters of what is evil; keep your minds fixed on what is good.

Be kind to one another with a brother's love, putting others before yourselves in honour;

Be not slow in your work, but be quick in spirit, as the Lord's servants;

Being glad in hope, quiet in trouble, at all times given to prayer,

Giving to the needs of the saints, ready to take people into your houses.

Give blessing and not curses to those who are cruel to you.

Take part in the joy of those who are glad, and in the grief of those who are sorrowing.

Be in harmony with one another. Do not have a high opinion of yourselves, but be in agreement with common people. Do not give yourselves an air of wisdom.

Do not give evil for evil to any man. Let all your business be well ordered in the eyes of all men.

As far as it is possible for you be at peace with all men.
Do not give punishment for wrongs done to you, dear brothers, but give way to the wrath of God; for it is said in the holy Writings, Punishment is mine, I will give reward, says the Lord.

But if one who has hate for you is in need of food or of drink, give it to him, for in so doing you will put coals of fire on his head.

Do not let evil overcome you, but overcome evil by good. Romans 12:9-21

What Christians Should Do (Colossians 3&4)

Not Carnality but Christ

If then you have a new life with Christ, give your attention to the things of heaven, where Christ is seated at the right hand of God.

Keep your mind on the higher things, not on the things of earth.

For your life on earth is done, and you have a secret life with Christ in God.

At the coming of Christ who is our life, you will be seen with him in glory.

Then put to death your bodies which are of the earth; wrong use of the flesh, unclean things, passion, evil desires and envy, which is the worship of strange gods;

Because of which the wrath of God comes on those who go against his orders;

Among whom you were living in the past, when you did such things.

But now it is right for you to put away all these things; wrath, passion, bad feeling, curses, unclean talk;

Do not make false statements to one another; because you have put away the old man with all his doings,

And have put on the new man, which has become new in knowledge after the image of his maker;

Where there is no Greek or Jew, no one with circumcision or without circumcision, no division between nations, no servant or free man: but Christ is all and in all. Colossians 3:1-11

The Christian's Character

As saints of God, then, holy and dearly loved, let your behavior be marked by pity and mercy, kind feeling, a low opinion of yourselves, gentle ways, and a power of undergoing all things;

Being gentle to one another and having forgiveness for one another, if anyone has done wrong to his brother, even as the Lord had forgiveness for you:

And more than all, have love; the only way in which you may be completely joined together.

And let the peace of Christ be ruling in your hearts, as it was the purpose of God for you to be one body; and give praise to God at all times.

Let the word of Christ be in you in all wealth of wisdom; teaching and helping one another with songs of praise and holy words, making melody to God with grace in your hearts.

And whatever you do, in word or in act, do all in the name of the Lord Jesus, giving praise to God the Father through him. Colossians 3:12-17

The Christian's Relationships

Wives, be under the authority of your husbands, as is right in the Lord.

Husbands, have love for your wives, and be not bitter against them.

Children, do the orders of your fathers and mothers in all things, for this is pleasing to the Lord.

Fathers, do not be hard on your children, so that their spirit may not be broken.

Servants, in all things do the orders of your natural masters; not only when their eyes are on you, as pleasers of men, but with all your heart, fearing the Lord:

Whatever you do, do it readily, as to the Lord and not to men;

Being certain that the Lord will give you the reward of the heritage: for you are the servants of the Lord Christ.

For the wrongdoer will have punishment for the wrong he has done, without respect for any man's position.

Masters, give your servants what is right and equal, conscious that you have a Master in heaven. Colossians 3:18-4:1

Christian Graces

Give yourselves to prayer at all times, keeping watch with praise;

And making prayer for us, that God may give us an open door for the preaching of the word, the secret of Christ, for which I am now in chains;

So that I may make it clear, as it is right for me to do.

Be wise in your behavior to those who are outside, making good use of the time.

Let your talk be with grace, mixed with salt, so that you may be able to give an answer to everyone. Colossians 4:2-6
