I made that decision in 1992 at the age of 44. My wife was a believer so I had some support through her.  However I was alone or so I thought.  I had never read the bible usless you count the time I read some of Ezekiel to dtermine if he was describing a UFO.  I new somehow that the Bible was truth.  So I started with the New Testament, then went to page one.  It didn't take me long to realize I had no idea what I was reading.  I sought out the only "Christian" I knew.  He brought me into a fellowship of men from all different denominations(a prayer group . . . I didn't vocalize a prayer for over 6 months).  I read books and of course continued in THE book, asking questions of the men in the fellowship.  Eventually  I was mentored by a godly man.  I also looked for venues to  further my relationship with Christ.  That is when I discovered Promise Keepers.  Men's small group ministry became the place where my relationship to men and to Jesus grew.  What do I do now that I have given my life to Christ?  READ, FELLOWSHIP WITH GODLY MEN, TALK TO GOD (PRAY) and ASK QUESTIONS.
