The Joy of Jesus and It's Blessing

Faith: Holy assurance delivers from those doubts and fears which rob many a Christian of his legitimate joy in the Lord. This is clear from the contrast presented in Romans 8:15, "For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba Father." Suspense is bad enough in any of our concerns, but most of all in connection with our eternal interests. But true assurance sets us free from the painful bondage of uncertainty, and even robs death of its terrors. It enables the soul to say, "I will greatly rejoice in the Lord, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation" (Isa. 61:10).
Holy assurance produces patience in tribulation: "And took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance" (Heb. 10:34). Where the heart is anchored in God, basking in the sunshine of His countenance, the Christian will not be afraid of evil tidings, remains calm under bereavements, is unmoved by persecutions. "When I live in a settled and steadfast assurance about the state of my soul, methinks I am as bold as a lion. I can laugh at all tribulation: no afflictions daunt me. But when I am eclipsed in my comforts, I am of so fearful a spirit that I can run into a very mouse-hole" (Latimer to Ridley, 1551).
Holy assurance results in a joy in God, which causes its possessor to despise those vaporous pleasures after which the worldling so much dotes. "Although the fig tree shall not blossom, neither shall fruit be in the vines; the labour of the olive shall fail, and the fields shall yield no meat; the flock shall be cut off from the fold, and there shall be no herd in the stalls; yd I will rejoice in the Lord, I will joy in the God of my salvation" (Hab.. 3:17, 18). "Wherefore the rather, brethren, give diligence to make your calling and election sure . . . for so an entrance shall be ministered unto you abundantly (both now and in the future) into the everlasting kingdom of our Lord and Saviour Jesus Christ" (2 Pet. 1:10, 11).
