Let that ethical philosophy therefore of free-will be far from a Christian mind.
Without knowledge of self there is no knowledge of God.
The Holy Spirit is the bond by which Christ efficaciously unites us to himself.
We are nowhere forbidden to laugh, or be satisfied with food...or to be delighted with music or to drink wine.
Our assurance, our glory, and the sole anchor of our salvation are that Christ the Son of God is ours, and we in turn are in him sons of God and heirs of the Kingdom of Heaven, called to the hope of eternal blessedness by God's grace, not by our worth.
Since we are all naturally prone to hypocrisy, any empty semblance of righteousness is quite enough to satisfy us instead of righteousness itself.
