Matthew 7:12 "So whatever you desire that others would do to you, do also to them, for this is the Law and the Prophets."
All the verbs in this text are in the present tense. In the Greek language the New Testament was written in, this means the verbs speak of continuous action. What we continually desire others to continually do to us we are to continually do to them. Jesus isn't speaking of a "one and done" action toward another person. What we desire others to do to us Jesus commands us to do for others continually.
Think about how you desire your spouse to treat you. Are you treating your spouse that way? How do you desire your fellow employees to treat you? Are you treating them that way? Do you desire your neighbors to be sensitive to quiet times in the neighborhood? Are you? We know well how we want to be treated! Jesus tells us to treat others as we desire to be treated.
What if I don't see changes in my spouse, my neighbor, my fellow employees, etc., do I stop treating them as I want to be treated and do to them what they are doing to me? No, that would be giving into sin and be participating in sin's destructiveness. If we continually obey the Lord, we will be blessed (Luke 11:28). We are to obey the Lord and leave the results to Him.
Please note the last half of verse 12, "for this is the Law and the Prophets". Jesus is saying that we are to love our neighbor as ourselves (Leviticus 19:18b). In Matthew 22:37-40 He states that "loving our neighbor as ourselves" is one of the two greatest commandments that all the Law and Prophets depend. When obey God's commands we are doing our part to break the destructive cycle of sin and open the door wide for God to work in the people around us.
