The Bible is clear:
We are a depraved people in need of a Savior. Because of the sin introduced in the Garden of Eden (Genesis 3), we are all born with a nature of sin, one of opposition and rebellion against God (Romans 5:12). Such sin against God results in spiritual death (Ephesians 2:1) and the due penalty for sin is eternal separation (2 Thessalonians 1:5-9).
Our sin is forgivable. But how?
Hebrews 9:22 says that without the shedding blood, there can be no forgiveness of this sin. And here is the greatest news: In His great love for us, and for His perfect pleasure and glory, God sent Jesus Christ, his only son, to pay that penalty for us by dying on the cross, and all who accept this free gift is granted eternal life, he gives us a new life, and the right to be called sons and daughters of God (Ezekiel 36:25-27, 2 Corinthians 6:8, John 3:16).
So how do you receive this great and wonderful promise?
It begins with conviction. Do you understand that you are a sinner, and without Christ, Hell is your certain destiny, but with Christ, Heaven is your present reality? You must be convicted of your sin and convicted of your need for a Savior.
Next is Confession. The Bible says in 1 John 1:9 that we must confess this conviction to God and he is faithful and just to forgive our sin and cleanse us of unrighteousness. This confession is a two part process: First, it is a belief in our heart that Jesus is who the Bible says He is as our Messiah. Secondly, we confess that belief by verbally asking Christ to save us (Romans 10:9).
Finally, rest assured of the Completion of your salvation! Once you have asked Jesus to be your Savior, you are “sealed with the promise of the Holy Spirit” (Ephesians 1:13). This means nothing can separate you from the love of the Father (Romans 8:38-39) and you will spend eternity with Him in Heaven (Philippians 3:20).
What happens next?
It is important that you join fellowship with a local body of believers in a Bible-believing and teaching church, and be baptized. Baptism does not save you, but is a symbolic action that is a public demonstration of how God “washed” your sins away. It is the first act of obedience for the new believer. Next, begin attending a small group Bible study where you can study God’s word with other believers and “grow in the grace and knowledge of Jesus” (2 Peter 3:18).
