A TRUE CHRISTIAN

Romans 12 gives a practical picture of what genuine Christianity looks like. A true Christian is not identified merely by church attendance, words, titles, or outward appearance. True Christianity is demonstrated by a transformed life—how we relate to God, ourselves, other believers, and even those who mistreat us.

1. A True Christian Fully Surrenders to God

Romans 12:1

“...present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.”

A true Christian does not give God only a portion of life. There must be total surrender.

To surrender means placing our bodies, plans, ambitions, relationships, possessions, abilities, and future in God's hands.

A living sacrifice means that every day we deliberately choose God's will above our own desires.

Luke 9:23 – “If any man will come after me, let him deny himself, and take up his cross daily, and follow me.”

Galatians 2:20 – “I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me...”

Abraham demonstrated surrender when God asked him to offer Isaac. Although Isaac represented Abraham's future and God's promise, Abraham was willing to surrender him to God (Genesis 22:1–12).

Key thought: You cannot fully follow Christ while still insisting on controlling every area of your life.

2. A True Christian Separates Themselves from the World

Romans 12:2

“And be not conformed to this world: but be ye transformed by the renewing of your mind...”

Christianity requires transformation, not conformity.

The world has its own values, standards, attitudes, language, priorities, and definition of success. A Christian must refuse to allow the surrounding culture to determine how they live.

1 John 2:15 – “Love not the world, neither the things that are in the world.”

2 Corinthians 6:17 – “Wherefore come out from among them, and be ye separate, saith the Lord...”

Separation does not mean avoiding people. Jesus interacted with sinners, but He was never influenced by their sin. Daniel lived in Babylon but refused to allow Babylon to enter his heart. Daniel 1:8 says, “But Daniel purposed in his heart that he would not defile himself...” A true Christian may live in the world, work in the world, and interact with the world, but should not be controlled by the world's values.

Key thought: Do not change your Christianity to fit your environment; allow Christ in you to influence your environment.

3. A True Christian Is Sober in Self-Assessment

Romans 12:3

“...not to think of himself more highly than he ought to think; but to think soberly...”

Be honest with yourself.

A true Christian must develop an accurate understanding of themselves.

Galatians 6:3 – “For if a man think himself to be something, when he is nothing, he deceiveth himself.”

2 Corinthians 13:5 – “Examine yourselves, whether ye be in the faith...”

Psalm 139:23–24 – “Search me, O God, and know my heart: try me, and know my thoughts...”

Do not exaggerate your strengths. Do not ignore your weaknesses. Do not pretend to be what you are not. Do not measure yourself only by comparison with others. Spiritual maturity begins when we can stand before God and say, “Lord, show me who I really am.” A person who is never honest about their weaknesses will struggle to grow.

Key thought: You cannot correct what you refuse to acknowledge.

4. A True Christian Serves in Love

Romans 12:6–11

“Having then gifts differing according to the grace that is given to us...”

God has given every believer gifts and abilities for the benefit of others.

Christianity is not simply about receiving; it is also about serving.

Romans 12:9 – “Let love be without dissimulation.”

Romans 12:10 – “Be kindly affectioned one to another with brotherly love; in honour preferring one another.”

Mark 10:45 – “For even the Son of man came not to be ministered unto, but to minister...”

Our gifts must operate through love. 1 Corinthians 13:1–3 teaches that spiritual gifts and great sacrifices without love accomplish nothing. Jesus Himself demonstrated servant leadership. When Jesus washed His disciples' feet in John 13:4–15, He showed that greatness in God's Kingdom is demonstrated through service.

Key thought: Your gift may open a door for ministry, but love determines the impact of your ministry.

5. A True Christian Supernaturally Responds to Evil with Good

Romans 12:17–21

“Recompense to no man evil for evil...”

The natural human reaction to evil is retaliation.

Someone insults you—you insult them. Someone hurts you—you hurt them. Someone rejects you—you reject them. Someone speaks badly about you—you speak badly about them.

But the Christian response is different.

Romans 12:19 – “Dearly beloved, avenge not yourselves...”

Romans 12:20 – “Therefore if thine enemy hunger, feed him; if he thirst, give him drink...”

Romans 12:21 – “Be not overcome of evil, but overcome evil with good.”

Luke 23:34 – “Father, forgive them; for they know not what they do.”

Acts 7:60 – “Lord, lay not this sin to their charge.”

This response is supernatural because it requires the power of the Holy Spirit. Jesus demonstrated it on the cross, and Stephen demonstrated the same character while being stoned. A true Christian refuses to allow another person's wrongdoing to determine their own character.

Key thought: When you repay evil with evil, evil has influenced you. When you overcome evil with good, Christ has influenced you.

THE MARKS OF A TRUE CHRISTIAN

1. Fully surrenders to God – Romans 12:1

2. Separates themselves from the patterns of the world – Romans 12:2

3. Is sober and honest in self-assessment – Romans 12:3

4. Uses their gifts to serve others in genuine love – Romans 12:6–11

5. Supernaturally responds to evil with good – Romans 12:17–21

CONCLUSION

A true Christian is not simply somebody who professes Christ, but somebody whose life is continually being transformed by Christ.

Christianity affects:

Your relationship with God — surrender.

Your relationship with the world — separation.

Your relationship with yourself — sober assessment.

Your relationship with believers — loving service.

Your relationship with enemies — overcoming evil with good.

Matthew 7:20 – “Wherefore by their fruits ye shall know them.”

The question therefore is not merely: “Am I a Christian?”

The deeper question is: “Can Christ be seen in the way I live?”
