Before one can respond to God one must realize their lost spiritual condition:
Isaiah 59:2; 1 John 3:4; Romans 3:23 – for all have sinned, and fall short of the glory of God
One must believe in God and in Christ Jesus through hearing his gospel:
Matthew 28:19-20; Hebrews 11:6; John 3:16; James 2:20-24; Romans 10:17 – So then faith cometh by hearing, and hearing by the word of God.
One must repent:
Luke 13:3 – I tell you, Nay: but, except ye repent, ye shall all in like manner perish.
Acts 17:30 – And the times of this ignorance God winked at; but now commandeth all men everywhere to repent
One must confess the name of Christ before men:
Matthew 10:32 – Every one therefore who shall confess me before men, him will I also confess before my Father who is in heaven.
Romans 10:9-10 – because if thou shalt confess with thy mouth Jesus as Lord, and shalt believe in thy heart that God raised him from the dead, thou shalt be saved:
Be baptized into Christ for the remission of our sins:
Mark 16:15-16 – And he said unto them, Go ye into all the world, and preach the gospel to every creature. 16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Acts 2:37-38 – …Men and brethren, what shall we do? 38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Galatians 3:26-27 – For ye are all the children of God by faith in Christ Jesus. For as many of you as have been baptized into Christ have put on Christ.
1 Peter 3:20-21 – Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water. The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ
Once inside Christ, one must live a life of faithful, loving, and obedience to Christ:
Revelation 2:10 – …be thou faithful unto death, and I will give thee the crown of life.
If you have not obeyed the gospel, why are you still waiting?
Acts 22:16 – And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on his name.
