WHAT IS A CHRISTIAN?
A Christian is one who, having understood the ABC of the gospel of Christ, has received Christ, has taken his stand upon Him, and experiences salvation through him.
(a) When the Christian first believed, he experienced salvation, e.g. he was washed, sanctified and justified (1 Cor. 1:18). He was enriched by Christ (1 Cor.1:5) He found the cross the power of God (1 Cor. 1:18) and Christ became to him all he needed (1 Cor. 1:30) He continues to receive God's grace, he continues to be enriched by Christ(1 Cor. 1:5; 15:10; 16:23)
(c) He is delivered from his old state of sin (1 Cor. 15:17)
and he is freed from the power of sin (Rom. 8:2; 1 Cor. 6:12; 8:9)
(d) He knows the power of the Spirit in his life (1 Cor. 6:19,20; 12:7)
(e) He is kept by Christ (1 Cor. 1:8; 1 Peter 1:5)

WHAT IS FAITH?
Faith is both a decisive act and a sustained attitude. It begins as an act, by which a person abandons reliance on himself to merit salvation, has a firm conviction as to the truth of God's promises of mercy in Jesus Christ, and depends sincerely upon them. After this, faith becomes a habit of that person's life. Faith rests on certain facts which the apostles were careful to preach.
(a) Jesus is the Christ, the Son of God (John 20:31; Acts 9:20)
(b) He died for our sins (1 Peter 2:24)
(c) He was burried and was raised to life again on the third day (1 Peter 1:3; Rom. 4:25)
(d)His death and resurrection took place according to the manner in which God had promised beforehand in the Old Testament Scriptures (1 Cor. 15:3, 4)
(e) On the grounds of what Christ accomplished men may receive forgiveness and the gift of the Holy Spirit (Acts 2: 38,39)

WHAT IS REPENTANCE?
Repentance is turning from sin to God, as a result of a change of mind and heart about sin.
(a) God commands it on the part of all men. (Acts 17:30)
(b) Unless men repent, they will perish. (Luke 13:3, 5)
(c) Repentance is the first response demanded of men if they are to respond to the gospel of Jesus Christ. (Acts 2:38 )
(d) Repentance is the first condition God imposes if men are to find him. (Zech. 1:3,4; Acts 20:21)
(e) Repentance is a condition of cleansing, forgiveness, of salvation, of entry into the kingdom of heaven, of eternal life, for escaping the judgement of God upon sin. (Isa. 6:5; Luke 24:47; Acts 3: 19; 26:18; Matt. 4:17; Acts 11:18; Acts 17:30,31)
