And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith.
Philippians 3:9

God never asks us to do anything alone.  He is always with us giving us the ability and strength to accomplish whatever He requires.  What He requires of us He is requiring of Himself through us.  We can't forget where we came from and who we are now and why.  We don't always do the right thing or feel like the righteousness of Christ, but we are.  We are the sons and daughters of God and we owe all of who we are to Him.  Our flesh may desire credit for what we accomplish so you could say it is natural to feel gratified with ourselves. There is no one who could live the standard without the standard (which is Christ Jesus) dwelling within them. We receive from Him treasures of wisdom and knowledge, sanctification and redemption; equipped by His word and His Spirit for whatever service we have been called.  He began a work in our lives and will continue until the work is completed.  As Paul says in Galatians 3:3 We are foolish if we think we can begin in the Spirit but complete the work ourselves in our flesh.  To God be all the glory. 

Prayer 

Thank you for making me the righteousness of Christ.  Without Jesus I could not make it through a single day.  All that I am and all that I hope to be is because of Him and the Holy Spirit which dwells within me.  Let my life bear the fruit of your righteousness and bring glory to You. In You I trust.

Amen.
