Nothing more black or white than much fruit or no fruit. There’s no such thing as a little fruit or some fruit with Jesus.
Jesus is the true vine, we’re mere branches. You can appear fruitful, but whatever isn’t of His life and by His grace—is nothing.
Abundant fruit only comes from abundant life.
“I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing.” John 15:5
