An excellent summary of what it means to be a Christian!

John 3:16 and John 3:36 are a nice pair of verses that succinctly summarize what you have said from your heart:

John 3:16-19
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God's one and only Son. This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil.

John 3:36
Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on them.
