“Therefore seeing we have this ministry, as we have received mercy, we faint not” (2 Corinthians 4:1).
“For all things [are] for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God. For which cause we faint not; but though our outward man perish, yet the inward [man] is renewed day by day. For our light affliction, which is but for a moment, worketh for us a far more exceeding [and] eternal weight of glory; While we look not at the things which are seen, but at the things which are not seen: for the things which are seen [are] temporal; but the things which are not seen [are] eternal” (2 Corinthians 4:15-18).
“And let us not be weary in well doing: for in due season we shall reap, if we faint not. As we have therefore opportunity, let us do good unto all [men], especially unto them who are of the household of faith” (Galatians 6:9-10).
“In whom we have boldness and access with confidence by the faith of him. Wherefore I desire that ye faint not at my tribulations for you, which is your glory. For this cause I bow my knees unto the Father of our Lord Jesus Christ, Of whom the whole family in heaven and earth is named, That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, May be able to comprehend with all saints what [is] the breadth, and length, and depth, and height; And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God” (Ephesians 3:12-19).
