"“By their fruits ye shall know them” ( Matthew 7:20 ), the Saviour declared. All the true followers of Christ bear fruit to His glory. Their lives testify that a good work has been wrought in them by the Spirit of God, and their fruit is unto holiness. Their lives are elevated and pure. Right actions are the unmistakable fruit of true godliness, and those who bear no fruit of this kind reveal that they have no experience in the things of God. They are not in the Vine. Said Jesus, “Abide in Me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in Me. 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.” John 15:4, 5 . CT 329.1"
"Wherefore by their fruits ye shall know them."
Ellen White directly references Matthew 7:20 in this passage.
