Deuteronomy 5:16 “Honour your father and your mother, as the Lord your God has commanded you, so that you may live long and that it may go well with you in the land the Lord your God is giving you.
God’s commandments were carefully selected (by God, not Moses) to be easily remembered and essential to our Christian way of life. None are to grievous to follow, and yet all are broken regularly.
Christ’s reminder to the disciples was to love God and love our neighbours because all of the commandments become a whole lot easier to keep and follow when we do express our love towards others.
It’s not rocket science – it’s simple Christianity.
