Whatever you are facing ... choose to believe the Truth that God is for you. He will never forsake you. He will never leave you.
No matter what sorts of mistake, sin or failure you have made that lead you off God's wonderful path for your life - know God's mercy and grace are ALWAYS here to lead you back. God was continually gracious towards the Israelites despite their repeated effort to do things "their way". (read book of Judges).
Spiritual darkness (whether we bring it on or even if it is a result of spiritual warfare) can do one powerful thing for us. What is it? It can drive FAITH into the deepest parts of our being. It is in this place of darkness where we have to choose in what or in WHOM we will place our hope, our confidence and our trust in.
If you don't feel like you are on God's wonderful path for your life .... choose to TRUST Him today .... and follow the stepping path back towards Him. He will lead you into His perfect plan and will for your life ... and you choose to trust Him when you can not see what is ahead of you. Step out of the darkness .... by FAITH. By Faith, be it unto you!
"I will lead blind Israel down a new path, guiding them along an unfamiliar way. I will brighten the darkness before them and smooth out the road ahead of them. Yes, I will indeed do these things; I will not forsake them."
- Isaiah 42:16
