Romans 2:29b
And circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God.
In studying the the concept of "circumcision" of a heart. I noticed that there were effects from not allowing God to have His Way in our hearts. Stiff necks (they don't bow to God). Hardened hearts that are not soft toward God and to others. And ears that cannot hear the way God speaks to us. This is a good example of how when we study God's Word it can manifest on canvas.
