Tell the truth.
“The Law of Moses also says that you shall not break your vows – you must honor your vows to God. But I’m telling you something deeper – don’t make any vows! Don’t swear by heaven because it is God’s throne, and don’t swear by the earth because it is his footstool, or by Jerusalem because it is the city of David, our great king. Don’t even swear by your head, because you can’t change even a single one of your hairs white or black. Simply let your ‘yes’ mean ‘yes’ and your ‘no’ mean ‘no’. To say anything more than this is wrong.”
Go the 2nd mile.
“The Law of Moses says ‘An eye for an eye and a tooth for a tooth.’ But I’m telling you something deeper – don’t retaliate against someone who does wrong. If someone slaps you on one cheek, turn and offer him the other one. If someone sues you to take your shirt away, give them your coat as well. If someone demands that you carry a heavy load for a mile, carry it 2 miles instead. Give to anyone who asks and don’t refuse anyone who wants to borrow something from you.”
Love your enemies.
“You’ve been taught the message ‘Love your neighbor and hate your enemies.’ But I’m telling you something deeper – love your enemies and pray for people who persecute you. By doing this you will reveal yourself to be children of your Father in heaven. God makes the sun shine on those who are evil as well as those who are good, and God makes rain fall on the just and the unjust alike. How does it help you if you are nice only the people who are nice to you? Even sinful people can do that. If you welcome only your friends, how are you doing anything different than everyone else? Even people who don’t believe in God do that. Your goal is to be perfect, just like God is perfect.”
