…be content with such things as ye have: for He hath said, I will never leave thee, nor forsake thee. – Hebrews 13:5

Some years ago, under the apprehension of divine wrath, we were unhappy and troubled, so that we could find no rest; but now we are blessed in Christ so greatly that we are at perfect peace, and our soul has dropped its anchor in the haven of content. Our joy is usually as great as formerly our sorrow used to be. We feared our sorrow would kill us: we now sometimes think that our joy is more likely to do so, for it becomes so intense that at times we can scarcely bear it, much less speak it. As we could get no rest before, so now, by faith, we feel as if we never lost that rest, for we are so quiet of heart, so calm, so settled, that we sing, “My heart is fixed, O God; my heart is fixed!” …Getting God’s blessing upon everything, we have learned to be content, and something more: we joy in God through our Lord Jesus Christ. We used to fret before we knew Him; but His love has ended that. We thought we could do things better than God could, and we did not like His way of managing; but He has taught us to be like children, pleased with whatever our Father provides; and therefore we joyfully declare, “My soul is even as a weaned child: I have nothing to wish for. I want nothing but what my Father pleases to give me.” …Unto us who believe, Christ is precious-both treasure and honor in one: in fact, Christ is all. It is a delightful calm of mind which the believer enjoys when he dwells in Christ. Humble faith puts the soul into the guardian hand of the Redeemer, and leaves it there in the restfulness of entire trust. Grace baptizes us into blessedness. It plunges us into that sea of everlasting rest in which we hope for ever to bathe our weary souls. Yes, blessed be His name, the Lord Jesus has made life worth living! ~ C.H. Spurgeon
