The Joy of Jesus is to Grow in Love

"As the Father hath loved me, so I have loved you" (John 15:9). There is no change of theme, only another aspect of it. In the two previous verses the Lord had described three of the consequences of abiding in Him in order to fruitfulness; here, and in the three verses that follow, He names three of the varieties of the fruit home; and it is very striking to note that they are identical with the first three and are given in the same order as those enumerated in Galatians 5:22, where the "fruit of the Spirit" is defined. Here in John 15:9, it is love; in John 15:11, it is joy; while in John 15:12 it is peace—the happy issue of brethren loving one another.
"As the Father hath loved me, so have I loved you." "As the Father loved Him from everlasting, so did He love them; as His Father loved Him with a love of complacency and delight, so did He love them; as the Father loved Him with a special and peculiar affection, with an unchanging, invariable, constant love, which would last forever, in like manner does Christ love His people; and with this He enforces the exhortation which follows" (Dr. John Gill).
"As the Father hath loved me, so have I loved you; continue ye in my love." (John 15:9). Christ’s love to us is unaffected by our changeableness, but our enjoyment of His love depends upon our continuance in it. By this continuance in His love, or abiding in it, as it should be (the Greek word is the same), is meant our actual assurance of it, our reposing in it. No matter how mysterious His dispensations be, no matter how severe the trials through which He causes us to pass, we must never doubt His immeasurable love for us and to us. The measure of His love for us was told out at the Cross, and as He is the same to-day as yesterday, therefore He loves us just as dearly now, every moment, as when He laid down His life for us. To "abide" in His love, then, is to be occupied with it, to count upon it, to be persuaded that nothing shall ever be able to separate us from it. Dwelling upon our poor, fluctuating love for Him, will make us miserable; but having the heart fixed upon His wondrous love, that love which "passeth knowledge," will fill us with praise and thanksgiving. Very blessed but very searching is this. To "abide" in Christ is to abide in His love. Our growth proceeds from love to love.
