All true fruit which glorifies God, is the outgrowth of inward spiritual grace. It is an external manifestation of the Spirit of God abiding within.
John 15:4-5 ... 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.
Matthew 13:23 ... But he that received seed into the good ground is he that heareth the word, and understandeth it; which also beareth fruit, and bringeth forth, some an hundredfold, some sixty, some thirty.❤
