-- You are a sinner (Rom. 3, esp. v. 23)
-- The penalty for sin is death/hell (Rom. 6:23)
-- Jesus took the penalty for you on the cross (Rom. 5:15-21)
-- By God's grace alone, through faith alone, in Jesus Christ alone your sins are forgiven and you recieve abundant, eternal life right now (Eph. 2:8-9)
That's it. If you acknowledge that you are a sinner and put your faith in Jesus Christ, then you're saved from the just penalty for your sin; the penalty has been paid for you. You are adopted by God into his family. The Holy Spirit dwells in you. You have the capacity to live in a way you've never lived before. You may not yet have a good understanding of what any of that means, but you now have the rest of your eternal life to discover how blessed you've been. Christianity isn't just about going to heaven when you die (as if that weren't blessing enough). Jesus is offering you a life rich in the things that matter most, that are most valuable in the economy of the kingdom of God: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-controll (Gal. 5:22-23). You may be accustomed to trying to find those things from your circumstances (if you are, then you and I are in the same boat). My guess is that you've found that pursuit a bit frustrating (if you have, then you and I are in the same boat). The good news is that you (and I) now have access to the only one who truly offers life: Jesus Christ. Listen to him (read your bible) and speak to him (pray) and you'll begin to discover how wonderful this new relationship is.
Grace be with you.
