A Personal Relationship with God
The only way to Heaven and eternal life is to personally know Jesus Christ as your Savior.
You need to be saved because "all have sinned and come short of the glory of God" (Romans 3:23) and "the wages of sin is death" (Romans 6:23). "But God commends His love toward us in that, while we were yet sinners, Christ died for us!" (Romans 5:8)
We cannot save ourselves. We are saved "by grace through faith, and not of ourselves...not of works!" (Ephesians 2:8-9)
All we have to do to be saved, "born again," is to "confess with our mouth the Lord Jesus, and believe in our heart that God has raised Him from the dead! For with the heart man believes for righteousness. With the mouth confession is made for salvation (Romans 10:9-10).
