God loved the people of this world so much that He gave His only Son, so that everyone who has faith in Him will have eternal life and never really die
Sin pays iff with death
But God showed how much he loved us by having Christ die for us, even though we were sinful
But if we confess our our sins to God, he can always be trusted to forgive us and take our sins away.
So you will be saved, if you honestly say, "Jesus is Lord," and if you believe with all your heart that God raised him from death.
Everything in the Scriptures is God's Word. All of it is useful for teaching and helping people and for correcting them and showing them how to live.
