8Galatians 5:16-17

This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.  For the flesh lusteth after the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.

How many times have we wanted to do the right thing, and we let our flesh take over. Walking in the Spirit takes practice and intention.  We can choose our emotions and our focus whether it brings life to us or death.  Somedays we will do better than other days, we are human, and it does take practice. We have the choice to rule and reign in this life through our Spiritual life.  Our contentment relies on our focus and the flesh is never satisfied.
