Juan 15:3

“I am the true vine, and my Father is the husbandman.”

“Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit.”

“I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.”

“For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.”

“Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.”
