It’s not me who requires that it is followed but Jesus Christ. Following it is not a ‘law’ like the Mosaic law, but the result of His spirit abiding in us and perfecting us. It’s the transforming power of His love and grace that makes us want to obey Christ’s commandment and that enables us to obey it. (John 15)
So Mt 5:44 is a nice vision for the future and until then we can hate our enemies as much as we like? What unbiblical nonsense! There’ll be no more enemies in the Kingdom of Heaven. No evil can enter into it. We pray that His will be done in heaven and on earth. Christ sowed the seeds for the Kingdom of Heaven in us, and that’s where they should grow. If He is within us, the Kingdom of God is within us (Luke 17:21) and we are under its law right now.
And if one truly is in the Spirit, one will love all others, including one’s enemies.
You didn’t get as far as reading Gen 32-33? Never heard the story of Esau and Jacob reconciling, in which Jacob says to Esau “seeing your face is like seeing the face of God, since you have favorably accepted me. 11 So receive my blessing, which has been sent to you, since God has been gracious to me.”? It’s beautiful!
He died for their forgiveness as well as for yours. “Jesus said, “Father, forgive them, for they know not what they do.”” (Luke 23:34a)
Being born again is nothing that we can achieve via our own wisdom and strength. It involves more than just accepting some doctrine or the other without question. It means that we let our old selfish, vengeful and hateful self die. That we are being made new.
"17 Therefore this I say and testify in the Lord, that from now on you walk not as other Gentiles walk, in the vanity of their minds, 18 having their understanding darkened, excluded from the life of God through the ignorance that is within them, due to the hardness of their hearts. 19 Being calloused they have given themselves over to sensuality for the practice of every kind of impurity with greediness.
20 But you did not learn about Christ in this manner, 21 if indeed you have heard Him and have been taught by Him, as the truth is in Jesus: 22 that you put off the former way of life in the old nature, which is corrupt according to the deceitful lusts, 23 and be renewed in the spirit of your mind; 24 and that you put on the new nature, which was created according to God in righteousness and true holiness.
25 Therefore, putting away lying, let every man speak truthfully with his neighbor, for we are members of one another. 26 Be angry but do not sin. Do not let the sun go down on your anger. 27 Do not give place to the devil. 28 Let him who steals steal no more. Instead, let him labor, working with his hands things which are good, that he may have something to share with him who is in need.
29 Let no unwholesome word proceed out of your mouth, but only that which is good for building up, that it may give grace to the listeners. 30 And do not grieve the Holy Spirit of God, in whom you are sealed for the day of redemption. 31 Let all bitterness, wrath, anger, outbursts, and blasphemies, with all malice, be taken away from you. 32 And be kind one to another, tenderhearted, forgiving one another, just as God in Christ also forgave you." (Eph. 4:21-32)
