I Peter 2:4-5 Come to Christ, who is the living cornerstone of God's temple. He was rejected by the people, but he is precious to God who chose him. And now God is building you, as living stones, into his spiritual temple. What's more, you are God's holy priests who offer the spiritual sacrifices that please him because of Jesus Christ.
This is God's plan for all His people. We are created in Christ to serve Him as His chosen priests amongst men. We are not zombies roaming about on earth biding our time. We are living stones, actively doing the Lord's bidding. We are first and foremost spiritual beings. Who we are in Christ takes precedence over everything else.
We are holy priests before Him. We are not participants in sinful living. We are characterized by who we are in Christ and not who we are in the world. We are different because Christ makes us different. We are not perfect, but we are perfected in Him. And, the more we live in Christ the more we show it.
No matter who you may think you are or aren't, God says you are special. You are specially created in Christ for Him. You have a very important role to play in the work of the Kingdom. You are a somebody because God says you are. Your value is not measured by the world's standard; it's measured by God's standard. We must not listen to what others say about us or compare ourselves to anyone else.
We are a work in progress. The Lord is building you into His spiritual temple. He knows you are not who you need to be or will be. He will not stop working on you until He is ready to take you home. Be patient and don't let what may seem to you to be a lack of progress discourage you. The Lord will complete what He has begun in you.
Live like the person God says you are. The Lord believes in you. Believe you are who He says you are.
