1 Thessalonian 5:18 "Give thanks in all circumstances, for this is God's will for you in Christ Jesus."
I have seen way too many dissatisfied Christians over the years. These believers are not happy where God currently has them and sadly, they are missing some great opportunities. I've been there myself. When God moved us home from the mission field I wanted to go back. By focusing on where I wanted to be instead of where I was, I missed many opportunities to share Jesus with those around me.
1 Cor. 12:17-18, "If the whole body were an eye, how would you hear? Or if your whole body were an ear, how would you smell anything? But our bodies have many parts, and God has put each part just where he wants it."
Where does God have you now? It doesn't matter if you are in full-time ministry or not. God has you right where He wants you. Focus on Him and see what He wants you to do with what He has given you. Let God satisfy you in the here and now. Your situation may change in the future but you need to show faithfulness in the present. I have seen flowers that bloom transplanted to new locales, where they grow to be just as hearty as they were before.
Focus on Him and let Him use you where you are. Relax. He holds the future.
