Why Move Forward? (Philippians 3:12-16 (LD 44)

We conclude the teaching on the law of God from the catechism.  The tenth commandment is that we are not to desire anything that goes against the law of the Lord.  So, we know that we are not to desire something contrary to God, but we do which is why we sin.  How do we move beyond sin?  Do we conform to the Lord because it is better to conform to Him rather than not conforming to Him?
