God's Faithfulness and His Promises
Previously, we reflected upon God's ability in conjunction with His promises. The capability of the one making promises is strategic when promises are made. When relating God's ability to His promises, we have full assurance that He can fulfill what He has promised to do. "Ah, Lord God! Behold, You have made the heavens and the earth by Your great power and outstretched arm. There is nothing too hard for You…Behold, I am the LORD, the God of all flesh. Is there anything too hard for Me?" (Jeremiah 32:17, 27). Our Lord created all the universe, and He is ruler over all of humanity. Surely, He is able to fulfill all of His promises.
Now, we have another issue to consider: faithfulness. When promises are made, faithfulness is just as important as ability. It is vital to know that the one promising is not only able, but is also reliable. In our present verse, we are given reason to exercise unwavering confidence in God, based upon His faithfulness. "Let us hold fast the confession of our hope without wavering, for He who promised is faithful."
In the book of Hebrews, we are given a recurring call to stand firm in the hope of the Lord. To participate more and more in the reality of being God's spiritual household here on earth, we are to confidently embrace throughout our pilgrimage the hope that is available in our Lord: "whose house we are if we hold fast the confidence and the rejoicing of the hope firm to the end" (Hebrews 3:6). To fully partake of all that is ours in Christ, we are to persistently cling to Him by faith right up to our last days on earth. "For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end" (Hebrews 3:14).
Our present verse also stresses persistent faith in the hope of the Lord. "Let us hold fast the confession of our hope without wavering." This persistence of trust in God is related to His promises and His faithfulness. "For He who promised is faithful." We can cling tightly to the promises of God. We can confidently hope in God's fulfilling His promises to us. We do not need to waver in doubt, because God is reliable. He is trustworthy. He is faithful.
