1 Tim 1:12 (HCSB)
Where has God placed you? Some of us may respond well no where! "I am in this dead end job!" Or maybe you may say, "I really don't have any important role in the church or ministry." We may excuse ourselves by saying, "I really don't have any gifts, skills," even, "God can't use me." No, God has placed you where you are for His purpose. You have a ministry, whether you recognize it or not.
Notice three important things about Paul's statement to Timothy. First, He is thankful. Don't belittle where God has placed you but revel in it. God has placed you where you are to do what only you can do. Thank Him for using you there!
Second, notice that He says God has considered him faithful. Was Paul more faithful than us? Perhaps in some ways but over all no not really. He was human just like us. Sinful, some times stupid and not always doing what he should be and yet God considered him faithful. Understand what God understands about you. You are a work in progress. If you are waiting to be perfect, ready or prepared you probably will never be used. God considers us faithful not because of who we are but because of who we will be.
Third, just a reminder, God places us where He wants us. Ministry is not a choice it is our calling. We don't choose where and when we serve. God places us in His place and in His time.
Just serve where He has placed you!
