“When you fast, do not look somber as the hypocrites do … But when you fast, put oil on your head and wash your face, so that it will not be obvious to men that you are fasting.”
“Love your enemies and pray for those who persecute you.” … “Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you.” … “But love your enemies, do good to them, and lend to them without expecting to get anything back.”
“Do not store up for yourselves treasures on earth … store up for yourselves treasures in heaven.” … “Sell your possessions and give to the poor. Provide purses for yourselves that will not wear out, a treasure in heaven that will not be exhausted, where no thief comes near and no moth destroys.”
“… do not worry about your life, what you will eat or drink; or about your body, what you will wear. … Seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself.” … “Therefore I tell you, do not worry about your life, what you will eat; or about your body, what you will wear. Life is more than food, and the body more than clothes.”
“… go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.”
“Love each other as I have loved you.” … “This is my command: Love each other.”
Jesus said these things. Unless He was exaggerating, He wants us to do them. He knows that doing them will be good for us, good for the kingdom, good for others, good for the whole world.
Whether they are commandments or not.
So what would happen if we stopped fretting so much about things that we might or might not be authorized to do, and started diving headfirst into doing the things He has asked us to do – with all our heart, soul, mind and strength?
