“I didn’t know,” says the offender, who immediately hears “Ignorance of the law is no excuse.”
The concept rings true spiritually as well; the only requirement is to love God with all of our heart, mind, soul, and strength: the first commandment.
God made it this way because all wisdom, knowledge, and understanding come from Him; He reveals His will to those who fear Him.
He chose us; but we must respond in kind by choosing Him.
Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
Mark 12:30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
John 15:16 Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you.
James 4:8 Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded.
