1Pe 2:21-25 KJV 21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps: 22 Who did no sin, neither was guile found in his mouth: 23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously: 24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed. 25 For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.Rom 12:10

 KJV Be kindly affectioned one to another with brotherly love; in honour preferring one another;

 Joh 13:34-35 KJV 34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. 35 By this shall all men know that ye are my disciples, if ye have love one to another.

 Joh 13:3-17 KJV 3 Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God; 4 He riseth from supper, and laid aside his garments; and took a towel, and girded himself. 5 After that he poureth water into a bason, and began to wash the disciples' feet, and to wipe them with the towel wherewith he was girded. 6 Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet? 7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter. 8 Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me. 9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head. 10 Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all. 11 For he knew who should betray him; therefore said he, Ye are not all clean. 12 So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you? 13 Ye call me Master and Lord: and ye say well; for so I am. 14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet. 15 For I have given you an example, that ye should do as I have done to you. 16 Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him. 17 If ye know these things, happy are ye if ye do them.

Eph 4:31-32 KJV 31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: 32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.

Eph 4:22-24 KJV 22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; 23 And be renewed in the spirit of your mind; 24 And that ye put on the new man, which after God is created in righteousness and true holiness.

Mat 5:43-48 KJV 43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. 44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; 45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. 46 For if ye love them which love you, what reward have ye? do not even the publicans the same? 47 And if ye salute your brethren only, what do ye more than others? do not even the publicans so? 48 Be ye therefore perfect, even as your Father which is in heaven is perfect.

JESUS CHRIST LOVED US WHILE WE WERE YET SINNERS AND WE SHOULD ALSO LOVE PEOPLE EVEN THOUGH THEY ARE STILL IN THEIR SINS. 

Rom 5:6-8 KJV 6 For when we were yet without strength, in due time Christ died for the ungodly. 7 For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. 8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.

IT IS NATURAL TO LOVE YOUR FRIENDS. IT IS SUPERNATURAL TO LOVE YOUR ENEMIES. THAT IS WHY WE MUST BE TOTALLY SUBMITTED TO THE LORD JESUS CHRIST SO HIS HOLY SPIRIT MAY DWELL IN US. 

THEN IT IS NATURAL FOR US TO LOVE OUR ENEMIES. 

Rom 5:5 KJV And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.

1Jn 4:7-17 KJV 7 Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. 8 He that loveth not knoweth not God; for God is love. 9 In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. 10 Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. 11 Beloved, if God so loved us, we ought also to love one another. 12 No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us. 13 Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit. 14 And we have seen and do testify that the Father sent the Son to be the Saviour of the world. 15 Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God. 16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him. 17 Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
