Repentance is the language and action of surrender. Americans do not surrender. American Christians do not surrender. If sustaining unity, harmony, love, peace, and kindness in a congregation involves surrender, many Christians will justify division, confrontation, hate, animosity, internal war, and contempt. Repentance may be godly, but it is un-American.
Faith is important, but our common concept of faith is accepting facts.
That faith requires no surrender. You express faith, add a few new religious responsibilities to your life, and basically live like you always lived. Baptism is critical, but our common concept of baptism is little more than the physical act of immersion. That act is a matter of yielding to divine authority. You yield to authority, add a few new religious responsibilities to your life, and basically live like you always lived.
