The only fruit that will last is the fruit that grows on the cross

You did not choose me, but I chose you and appointed you that you should go and bear fruit. (John 15:16)

On the day after the night in which Jesus spoke these words to the eleven and to you, Glen, he laid himself down on the cross and bought you with his blood. You are now his fruit and his fruit-bearer. The only fruit that will ever endure to eternal life is fruit which grows out of the cross. “The hour has come for the Son of Man to be glorified. Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone, but if it dies, it bears much fruit” (John 12:23, 24). We are Christ’s fruit because he died for us. We are his fruit-bearers if we are willing to take up our cross and die with him. Never forget the setting of your text, Glen. It is no accident that when Jesus had commanded you to go and bear fruit, he went and died. Your call and your ministry must always stand in the shadow of the cross of Christ. The only fruit that will last is the fruit that grows on the cross.
