Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them. (John 3:36 NIV)
Salvation only comes through true belief in Jesus Christ. If you have truly repented of your sins and trusted in Christ for salvation, you will become more like Christ. Christ-like love will be the hallmark of your existence.
If you are not really sure who Jesus is, then you need to find out. If you have never read through the New Testament, than pick one of the gospels and read it all the way through. The four gospels are: Matthew, Mark, Luke, and John. If you are not a good reader you may want to start with Mark, because it is the shortest. This will only take you a couple hours at most.
