Rejoiceth not in iniquity, but rejoiceth in the truth. 1 Corinthians 13:6.
Love "rejoiceth not in iniquity, but rejoiceth in the truth." He whose heart is imbued with love is filled with sorrow at the errors and weaknesses of others; but when truth triumphs, when the cloud that darkened the fair fame of another is removed, or when sins are confessed and wrongs corrected, he rejoices.--Testimonies for the Church 5:169.
"Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently." 1 Peter 1:22.
The Word of God--the truth--is the channel through which the Lord manifests His Spirit and power. Obedience to the Word produces fruit of the required quality--"unfeigned love of the brethren." This love is heaven born, and leads to high motives and unselfish actions.--The Acts of the Apostles, 520.
"Love is never glad when others go wrong, love is gladdened by goodness, always slow to expose, always eager to believe the best." 1 Corinthians 13:6, 7, Moffatt.
