“The First Commandment, ‘Thou shalt have no other gods before Me’: My friend, are you ready to be weighed against this Commandment? Have you fulfilled, or are you willing to fulfill all the requirements of this Law? Put it into one of the scales, and step into the other. Is your heart set upon God alone? Have you no other God? Do you love Him above father or mother, the wife of your bosom, your children, home or land, wealth or pleasure? If men were true to this commandment, obedience to the remaining nine would follow naturally. It is because they are unsound in this that they break the others.” D. L. Moody
Deuteronomy 30:10if you obey the voice of the Lord your God, to keep His commandments and His statutes which are written in this Book of the Law, and if you turn to the Lord your God with all your heart and with all your soul.
