Can I be sure I will not go there?
Yes. John wrote so that those who believe in the name of the Son of God may know they have eternal life, and Jesus said whoever believes has passed from death to life.
Being sure does not come from being good enough. It rests on what Jesus has done and on His promise.
13These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.
