I have never known anyone to express regret for meeting the Lord.
I have heard many say they wished they had prayed more, yielded to Him more quickly and learned more of God's Word.
Look at what the Lord has done in your life. How do you know He is real? How has He answered prayer? What hope He has provided! He has met your every need. He has planted you in the Body and He has knit you in with Love.
You have Ebeneezer stones in your life. Tell about them. Report over and over the different ways you have seen the reality and provision of God.
It never gets old. The more you repeat it, the newer it gets.
