1 John 3:20

Look within, for man cannot judge whom he cannot see. If "we assure our heart," let it be "before Him." Because "if our heart think ill of us," i.e. accuse us within, that we do not the thing with that mind it ought to be done withal, "greater is God than our heart, and knoweth all things." Thou hidest thine heart from man: hide it from God if thou canst! How shalt thou hide it from Him, to whom it is said by a sinner, fearing and confessing, "Whither shall I go from Thy Spirit? and from Thy face whither shall I flee?" He sought a way to flee, to escape the judgment of God, and found none. For where is God not? "If I shall ascend," saith he, "into heaven, Thou art there: if I shall descend into hell, Thou art there." Whither wilt thou go? whither wilt thou flee? Wilt thou hear counsel? If thou wouldest flee from Him, flee to Him. Flee to Him by confessing, not from Him by hiding: hide thou canst not, but confess thou canst. Say unto Him, "Thou art my place to flee unto," and let love be nourished in thee, which alone leadeth unto life. Let thy conscience bear thee witness that thy love is of God. If it be of God, do not wish to display it before men; because neither men's praises lift thee unto heaven, nor their censures put thee down from thence. Let Him see, who crowneth thee: be He thy witness, by whom as judge thou art crowned. "Greater is God than our heart, and knoweth all things."

He had said, "Let us not love only in word and in tongue, but in work and in truth:" we are asked, In what work, or in what truth, is he known that loveth God, or loveth his brother? Above he had said up to what point charity is perfected: what the Lord saith in the Gospel, "Greater love than this hath no man, that one lay down his life for his friends," this same had the apostle also said: "As He laid down His life for us, we ought also to lay down our lives for the brethren." This is the perfection of charity, and greater can not at all be found. But because it is not perfect in all, and that man ought not to despair in whom it is not perfect, if that be already born which may be perfected: and of course if born, it must be nourished, and by certain nourishments of its own must be brought unto its proper perfection.
