The truth for those who are in Christ is that it is always greener where God is. He leads us to rest in green meadows. And there He renews our strength. He protects and comforts us. So we have no need to be afraid. We have no reason to turn aside from the presence of God.
Don’t be overwhelmed by the troubles you are going through. Keep everything in perspective. Encourage yourself in the Lord your God. Remember what God has done in your life and in the world. Pray for yourself, it is okay to do that. More importantly pray to establish your connection with Him. Realize that God is in control. Your times are in His hand and you can trust Him and finally, ask God what to do -- "Lord lead me, I will follow."
Preaching through the Bible is fun! We get to see somethings that our faith needs to encompass but not focus on. If you are struggling with some strongholds in life its time to get some help. Go see a good Christian counselor. Even if you are not you need to start learning to use God’s weapon of His word and prayer.
David had this great destiny! He was to be King. Even he was put out to pasture for a while. Remain in Him. Remain faithful. Keep giving! Keep volunteering. You say I can’t I’m stuck in Philistine territory, the wilderness. Listen that is no excuse to stop doing. To stop living. To stop abiding in our Christ. He will make the impact. You remain faithful.
