We all have a testimony of when and how we came to faith. But we also have an ongoing testimony as we never fully arrive in this life.
I observe my continued testimony thus:
1st was coming to faith in '89.
2nd was my growing and walking with the Lord for several years, creating a strong foundation by studying Scripture everyday, many days for up to 8 hours a day (I'd be engrossed until 2 in the morning at times). This helped me get a head knowledge of the Word and what God wanted me to know. However, reading is not a substitute for experience. That would come with suffering and seeing my sin for what it truly is.
That brings me to 3rd and current. Starting in 2005 when I had my 1st back surgery, then my Bible and study notes were stolen from my truck in 2006. This sent me from looking outward to looking inward. I began to suffer physically with multiple surgeries, addiction to pain killers, bitterness at life and God. I began over the last decade to see my own sinful nature - not just understand it from a head knowledge, book smart kinda way - but to truly "get" just what God has forgiven in us. I've seen the ugly, enemy of God sinful nature side of myself. I obviously don't like it, but I'm finally beginning to understand.
I am now weened off all medications and maintained by only 3 to 4 tablets a day (I finally asked the Dr and my amazing wife to help me as I knew I had a problem).
I've purchased another Bible just like the one stolen from me and am transferring all my notes to it... sort of a "new beginning"
I now feel the Spirit opening my eyes and heart to those outside of myself.
All in all I must say, I have not liked the last decade much... but I wouldn't change it for anything. It's shaped me into who I am now becoming.
God is good, all the time... even when life is unfair, we're suffering unimaginable pain and loss, and we're mad at Him. He is still there for us. I thank Him for not abandoning me and look forward to my ongoing testimony.
