The Bible teaches that obedience to God is necessary for salvation. God’s plan of salvation requires the following:

Hear the truth of God’s word. Jesus teaches the importance of hearing: John 5:24-25
Believe in God, and that Jesus Christ is HIS only begotten son: John 3:16-18, Acts 16:31, Romans 10:17, Hebrews 11:6
Repent of your sins: Luke 13:3-5, Acts 2:38, 3:19, 17:30 II Peter 3:9
Confess before man that “Jesus is Lord”, Romans 10:9-10, I John 4:15
Be Baptized for the remission (or payment) of your sins: Acts 2:38, 22:16, Mark 16:15-16, I Peter 3:20-21
Then add to your faith all the qualities mentioned in I Peter 1:5-11
