Christianity 101: Basic Christian apologetic when sharing the Gospel

Who is Jesus?

  • Jesus is a historical figure.
  • He is God, born through a virgin birth and human in every sense.
  • He gave His life on the cross to save us from hell; His blood shed for the forgiveness of our sins, once and for all time. ( 2 Cor. 5:21; Rom. 6:9-10; Heb. 9:22)
  • Jesus resurrected to prove He has power over death; those who believe will also resurrect to be with Him in heaven for all eternity.

The deity of Jesus in Scriptures

John 1:14, John 8:58, John 10:30-33, John 11:25-26, John 20:28, Colossians 2:9, and Hebrews 1:3-9. Read more Bible verses about the deity of Jesus.

Propitiation: Jesus the “Lamb of God”

God presented Jesus as a propitiation through faith in His blood, to demonstrate His righteousness because in His restraint, God passed over the sins previously committed. (Romans 3:25)

Animals were used as “sin offering.” John the Baptist (v 1:29) welcomes Jesus “Behold, the Lamb of God, who takes away the sins of the world!”

Why is Jesus Called “Lamb of God”

Hebrews 10:4
It is not possible for the blood of bulls, goats (or literal lamb) to take away sins.

Why should we share the Gospel?

It is only destined for man to die once after which is judgment; if your name is not in the Book of Life, the lake of fire awaits (Heb. 9:27; Rev. 20:12). On the other hand, a new heaven and earth await those who belong to Christ, God’s children.

  • The world, as we know it is coming to an end. Love compels us to let others know they can be saved. (1 John 4:19).
  • Jesus commanded us to spread the good news of salvation (Matt. 28:19).

Sharing the Gospel is not converting someone to a religion

Jesus alone saves (Romans 3:23, Acts 4:12). Not by church membership, not by doing good works and boasting about it (Ephesians 2:8-9), and not by rituals.

Jesus alone saves, not by church membership.

The Gospel in a nutshell

Christ died for our sins in accordance with the Scriptures. He was buried, raised on the third day, and he appeared to all the apostles. (1 Corinthians 15:1-8)

God is a Good, Holy, and Just

“Sin and holiness” have no fellowship. If God is just, we deserve punishment for our sins. The Jews offered “animal sacrifice” to remove the “guilt of sin” (Heb. 10:1-18), but it cannot remove sin – we are lost.

Just as God provided Abraham a lamb, He gave us Jesus, the “lamb that was slain” to redeem us from sin, once and for all time. (John 3:16; Rom. 6:10)

Hebrews 9:22
Without the shedding of blood, there is no forgiveness of sin.

Boasting about our good works is nothing

Even if one can perfectly obey the commandments, all our righteous deeds are like filthy rags before a Holy God (Isaiah 64:6). We are saved by grace alone; it is a gift, not by our works, so that no one could boast. (Ephesians 2:8-9)

We become God’s child because of Christ

All things hold because of Jesus, and we become co-heir with Christ and shall inherit the new heaven and earth through Him. He clothes us with righteousness before God. (Col 1:17; Rom 8:17; Rev. 19:8)

John 1:12-13
But to all who did receive Him, He gave them the right to be children of God, to those who believe in His name, who were born, not of blood, or of the will of the flesh, or of the will of man, but of God.”

Repentance is important in coming to Christ

The Greek word for repentance is metanoeō. It means “to perceive or understand.” It is a mental activity. Jesus said, “Repent, for the kingdom of heaven is at hand” (Acts 3:19; Mat. 4:17). He used the verb form of repentance, which refers to changing one’s mind about sin.

When the thief on the cross asked Jesus to bring him to paradise, his faith saved him. He changed his mind on who Jesus is and believed He is the true Messiah. Even demons believe who Jesus is but they cannot repent. They are definitively separated from God, they have no savior. They are merely awaiting their punishment (Matthew 8:29). But we have hope in Christ.

The ABC of responding to the Gospel

A – Admit you are a sinner and commit to a path of daily repentance and sanctification, desiring to be Christ-like and not of this world.

  • Romans 3:23  (All have sinned)
  • Romans 5:8 (Christ died for us)

B – Believe in Jesus. He is God, the only name given to man by which we can be saved. Receive Him as your Lord and Savior.

  • Romans 6:23: (Sin is death, Christ is a gift of God)
  • Romans 8:1: (No condemnation with Christ)
  • Acts 4:12 (Jesus alone saves)
  • Ephesians 2:8-9 (We’re saved by faith in Jesus)

C – Confess that Jesus is Lord! Proclaim Him by being baptized with water.

  • Romans 10:9 (Declare Jesus is Lord!)
  • Romans 10:13 (Call on Jesus)

What is our assurance of salvation?

  • Romans 8:1 (No condemnation with Christ)
  • Romans 8:16 (Spirit testifies we are God’s children)
  • 1 John 5:12-13 (We have eternal life through Jesus)

The process towards Christian maturity

It is only by faith (believing) in Christ we are saved. However, as evidence of faith, we strive for sanctification. This is our response to God’s Holiness. If we love Jesus, we will obey His commandments and so “Bear Fruit.”

Process of sanctification
We bear fruit
We disciple others

Why is sanctification important?

We are saved by faith alone. God calls Christians to purity. Although sin is forgiven, a person who deliberately sin (did not repent) will find it difficult to have fellowship with a Holy God. We should walk in the light, not in darkness. (Hebrews 10:26)

1 John 1:7
If we walk in the light as He Himself is in the light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin.

Why Christianity is the only faith that matters

  • The Bible is the only book that tells who God is, creation, prophecies, and the salvation of humanity. The rest of the religions are about a Moralistic Deism.
  • Compared to other manuscripts like Plato or Home’rs Iliad, the Bible has over 25,100 documents discovered with a 99.5% textually pure. Plato’s work only has seven surviving copies of his works, Homer’s Iliad, with 643 copies. [CARM]
  • Next in popularity, Islam established 600 years after Jesus. Devout Muslim Intellect Nabeel Qureshi investigated Christianity for 15-years. He left Islam for Jesus.
  • Only Christianity has the “Living God,” other religions have dead or imaginative gods.
  • Only Jesus resurrected and demonstrated power over nature, demons, and life itself.
  • Today, Jesus continues to reveal himself in places like China and Iran through visions and dreams.

What happens when we become Christians?

1 John 5:1-4
Whoever believes that Jesus is the Christ is born of God, and whoever loves the Father loves the child born of Him. By this, we know that we love the children of God when we love God and observe His commandments. For this is the love of God, that we keep His commandments; and His commandments are not burdensome. For whatever is born of God overcomes the world; and this is the victory that has overcome the world—our faith.

  • The Holy Spirit assures us of salvation.
  • We have daily repentance that leads to daily sanctification.
  • With a teachable heart, we seek God’s words every day.
  • As godly people, we pray multiple times a day and walk in the Spirit.
  • We begin to “bear fruit” and develop the “mind of Christ.
  • Our heart’s desire is humility, integrity, and a thankful heart.
  • We learn to walk by faith, not by sight; fame and success are insignificant.
  • We seek to do good things because God’s love flows through us.
  • If our faith is genuine, the evidence of a “changed life” must show.
  • Sharing the Gospel becomes our lifestyle.
