“This is my commandment, that you love one another, as I have loved you.”  
John 15:12
“…You shall love your neighbor as yourself,”  Matthew 19:19
“But I say to you, love your enemies, and pray for those who persecute you.”  Matthew 5:44

But love all people?  Impossible with the kind of love that emanates from mankind!  This love is God’s love, agape, and it is seen in the gift of His Son:
“By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.  In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.  Beloved, if God so loved us, we also ought to love one another.”  1 John 4:9-11

God’s love was not drawn out by any goodness on man’s part (we were at enmity with Him), it was the act of Divine Will, a deliberate choice that emanates from the nature of God Himself.

The Lord Jesus Christ is the perfect expression of love and as He lives in us, it is He who manifests this love. Christian love is the fruit of His Spirit in the Christian!

Vine’s Expository Dictionary says,
Quote:
“Christian love, whether exercised toward the brethren, or toward men generally, is not an impulse from the feelings, it does not always run with the natural inclinations, nor does it spend itself only upon those for whom some infinity is discovered.  Love seeks the welfare of all (Romans 15:2, “Let each of us please his neighbor for his good, to his edification.), and works no ill to any (Romans 13:8, “Owe nothing to anyone except to love one another; for he who loves his neighbor has fulfilled the law.”); love seeks opportunity to do good to ‘all men, and especially toward them that are of the household of the faith,’ (Galatians 6:10, “So then, while we have opportunity, let us do good to all men…”)  End of quote.

I am sure you all can turn to the Scripture that describes this love; 
1 Corinthians 13:4-8b.  To me Galatians 5:22-23 does exactly this as well. These verses list nine fruit of the Spirit and I like to look at love as the fruit and the eight words following as the description/definition of this love.
(Compare it with the 1 Corinthians Scripture.)
“But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law.”
Galatians 5:22-23

It is only in Christ Jesus and by the control of the Holy Spirit can we love the way we are called to do.  So let us therefore draw near to the throne of grace and yield to the will of God in this commandment to 
‘Love one another just as Christ also loved us.’

“Walk in love, just as Christ also loved you…”  Ephesians 5:2
“…as He is, so also are we in this world.”  1 John 4:17

All praise to the only wise God our Savior now and forever.  Amen
