This truly goes against our human nature, and it definitely takes thought and genuine concern to pray for blessing and good to come to one's enemy. Praying for soundness and fairness in thinking, and working to make sure we do no harm to that individual are difficult, yet in preparing us for our future responsibilities, this is what God wants from us.
John O. Reid (1930-2016)
Out of the Abundance of Our Prayers
We cannot be perfect apart from others. The Bible links perfection with human relationships. Christ urges us to be as perfect as our Father in heaven and ties the process to how we treat each other. The Kingdom of God is about eternal, peaceful relationships. We cannot withdraw from people and still develop the necessary relationship skills, just as God never leaves us but continues to work with us. Life would be easier for Him if He ignored us, but He works on, helping us develop our relationships with Him. He is the One who works perfection in us.

Basic Doctrines: Going On to Perfection
Jesus says this to help us grasp the marvelous, obliging, and almost overwhelming generosity and magnanimity of God's approach toward His creation. He acts this way despite all that we have thoughtlessly and self-centeredly done against Him personally and His creation, which certainly includes other people both converted and unconverted. Regardless, He still gives and gives some more. Why? Because this is the way that He is by nature, setting us an example of what He wants us to become in our natures too.
Do not be misled, though. He is not a thoughtless, wealthy, spendthrift sap. He does all this giving with purposeful wisdom, and especially so with His children that He is now preparing for His Family Kingdom.
When dealing with His children, His giving nature does not change. It is, however, more directed and focused on their preparation for their future in His Kingdom. Yes, He directly tests us, but because we are the apple of His eye, He provides us with the comfort and encouragement of I Corinthians 10:13:
No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it.
Thus, we are given assurance that even in the midst of the difficulties necessary for our preparation to inherit the Kingdom as co-heirs with Christ, He will generously supply our needs.

Living By Faith and God's Grace (Part Two)
These verses contain perhaps the most startling, sublime statement Christ made. Jesus does not mean that we resolve to like everyone, but that we act in goodwill toward those we do not like as well as those we do. This command seems unreasonable and absurd, but only because of our carnality. Christ desires all to be happy. Both the hater and the hated are miserable to some degree, and the misery will not cease until the hatred dissolves. The antidote to hatred is love.
Some have described this love as an unconquerable goodwill, an invincible benevolence. This love does not merely involve feeling, but also the will. With this love, our concern for another's good overcomes any feelings of offense, resentment, and retaliation. It motivates us to do good rather than react in kind to what caused our negative feelings toward the other. Only those who have the mind of Christ can do this. We must seek it from God.
In this section Christ lists three ways people show their ill-feelings toward others. Cursing indicates verbally denigrating others and working to destroy their reputation; gossiping. Hatred implies an active, passionate feeling against another. Spitefully using and persecuting means continually at war with, harassing, always being on another's case.
He also specifies three ways a Christian can combat these actions. We can bless, meaning giving good words for bad. We can also do good for our enemies, not merely restrain ourselves from retaliation. Lastly, we can pray for them and for their welfare, asking God to change their hearts so a two-way love can exist.
This is a major test for God's children. God wants us to do this so that we may resemble Him—be in His image—because this is the way He is. If a man has this love, he is like God. God shows us His love in this very manner. Despite what we do on His great green earth, the sun still shines, the rain still falls, and He is constantly providing for and working toward our salvation.

The Sixth Commandment (Part One) (1997)
Two wrongs do not make a right, and in our irritated or angry impatience, we frequently say or do something just as bad or worse as was done to us! Then where are we? Often, our patience does not delay our wrath as God's does.
The obvious meaning of Paul's advice is that we should not take vengeance. In Romans 12:19, Paul repeats this more plainly:
Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, "Vengeance is Mine, I will repay," says the Lord.
This, in turn, feeds directly into Jesus' teaching in Matthew 5:39-45, where Jesus' consistent instruction is that we not set ourselves against an evil person who is injuring us, whether verbally, physically or judicially. Rather, Jesus teaches us to be willing to give the offender something that might defuse the immediate situation—and perhaps even provide some small example that will promote his eternal welfare. Patience is of great value in this respect.
This in no way means we are weak, though to them we may at first seem so. Nor does it mean that we approve of their conduct. Though we may hate their conduct and suffer keenly when it affects us, Christ tells us to bless them, meaning we should confer favor upon or give benefits to them. We can do this by wishing the person well, speaking kindly of and to him, and seeking to do him good.
Situations like this may be the most difficult test we will ever face. Patiently deferring retaliation and committing the circumstance to God's judgment are indispensable to the best possible solution. But the primary point of Jesus' instruction, however, is not how to resolve these situations, but that we may be children of our Father. By imitating God's pattern, we will resemble Him and take a giant stride toward being in His image.

The Fruit of the Spirit: Patience
God's gracious gifts are just that—gracious. They are unearned and unmerited by us who have willingly sinned against Him, desecrated His beautiful creation and either ignored or neglected His awesome purpose. Despite this, His gifts of life are nonetheless unforced, an abundant manifestation of His kind nature. He does not return evil for evil; He does not bear grudges, burn with resentment, or plot to get even. Rather, He freely gives even to evil doers while He patiently works toward the completion of His purpose!
It has always been this way. Despite the Israelites' manifold sins after their rescue from Egypt, He continued to provide food, water, and protection all the way into the Promised Land. Once in the land, they continued their provocations for about another seven hundred years before He finally drove them into captivity. All the while He provided for them so abundantly that Israel became a very wealthy, albeit ungrateful, nation.
Psalm 78:37-39 records this of Israel's relationship with God:
For their heart was not steadfast with Him, nor were they faithful in His covenant. But He, being full of compassion, forgave their iniquity, and did not destroy them. Yes, many a time He turned His anger away, and did not stir up all His wrath; for He remembered that they were but flesh, a breath that passes away and does not come again.
