"By this shall all men know that ye are my disciples, if ye have love one to another" John 13:35. There it is, an acid test of discipleship. If love is lacking, so is proof of genuine discipleship. We're not left to question the kind of love involved. "This is my commandment, That ye love one another, as I have loved you" John 15:12.
So how, exactly, does Jesus love us? Peter's description would be accurate. "love one another with a pure heart fervently" 1 Peter 1:22, but there is still more.
When we are out in public among the everyday masses, we likely give little notice of others beyond perhaps a smile or "hello". "But when he (Jesus ) saw the multitudes, he was moved with compassion on them, because they fainted, and were scattered abroad, as sheep having no shepherd. Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few; Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest" Matthew 9:36-38. Where there is genuine love, there will be compassion, that deep sympathy and concern for others in need as well as a desire to help meet that need. It is that loving compassion that drives us to see the need for more laborers and therefore affects our prayers.
Jesus was very clear in typifying His disciples as those who meet the needs of others. It is actually a characteristic of the saved. "Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was an hungered, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. Then shall the righteous answer him, saying, Lord, when saw we thee an hungered, and fed thee? or thirsty, and gave thee drink? When saw we thee a stranger, and took thee in? or naked, and clothed thee? Or when saw we thee sick, or in prison, and came unto thee? And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me" Matthew 25:34-40. Obviously doing for others for recognition rather than from love is not what Jesus was talking about. He said "But when thou doest alms, let not thy left hand know what thy right hand doeth" Matthew 6:3.
Jesus wants us to love as He does. What He asks of us, He makes possible; therefore, we can ask of Him for His kind of genuine love and compassion knowing that "every one that asketh receiveth"
