LET GO... LET GOD!
I don't know about you, but there has been times in my life where, slowly but surely, the fire I once had in my spiritual walk began to fade. I often wrote it off as not being in the right church, hearing the right messages or listening to the right music (although each of those things are extremely helpful in one's spiritual walk). The bottom line is, I had to come to an understanding that my faith doesn't grow on trees, doesn't come from a vending machine and doesn't happen unless I personally do things that keeps it growing, on fire, healthy and alive.
The real queston I had to ask myself is, "Do I really want what God wants for me?" Do I really believe that God has my best interests in mind and ultimately knows what is best for me. For me, the answer is YES! I can't tell you how many times I have attempted to live my life on my own strength - still a Christian and still going to church - but running my life on my own way of thinking, never considering what God truly thought; afterall, I was a Christian and attended church... how could I go wrong.
"For just as the heavens are higher than the earth, so my ways are higher than your ways and my thoughts higher than your thoughts." - Isaiah 55:9 (NLT)
When dealing with personal sin, situations, people, decisions, etc., it is always a good idea to pray, "Lord, You know, sometimes, I don't want to let go of what I know and You know I need to let go of. So... help me to want what You want for me."
When you get to the point where you want what God wants, then and only then will you be pointed in the right direction.
Blessings to you!
