We do this ethical dance between the world of the Spirit and the world of the flesh in a vain attempt to have our cake and eat it too. Worship belongs to the world of the Spirit. Business belongs to the world of the flesh. Saturdays belong to the world of the flesh. Prayers belong to the world of the Spirit.
Checkbooks belong to the world of the flesh.
But what this actually does is divide our souls. We fool ourselves into thinking we are close to God, when our worship has become an empty sham and an embarrassment to God. We turn spirituality into religion, a set of rules replacing love, a list of laws we obey or principles we believe which actually hold God at arm's length and keep God from taking hold of us in our hearts. And we lose our integrity, the integration of spirit and flesh. You cannot separate the world of the Spirit and the world of the flesh, for, as Paul told the church at Corinth, you worship God in your flesh, through your flesh, when your flesh is directed by the Spirit of God.
