There are lots of ways to share the gospel. There are lots of kits, canned methods, and there are lots of conferences and seminars that will teach you how to do it. I have become frustrated with some and excited at the simplicity and the biblical teaching of others. Christianity Explored definitely falls in the camp of being solid and biblical.

God sent His Son (Jesus) into the world as King. We've rejected the loving King by sinning but Jesus died so that His blood would be poured out for many. He took the punishment that we deserve. We can become children of God when we repent of our sins and trust in Christ. This is good news. Really good news!
