That God is a faithful God is a fact that many people, myself included, can attest to. It is often said that God is "faithful to the end." While this is, in my mind, doubtless true, I posit that there may be meaning behind such a statement that you may not see at first glance.
God is always faithful. He will never leave us nor forsake us (Deut 21:6,8). He is faithful even when we are faithless (2 Tim 2:13). The Bible also states that His love towards us is great and His faithfulness endures forever (Psalm 117:2). But is there more to that phrase than just God's enduring faithfulness? I believe there is. God is faithful to the end. His word declares that God has a plan for each of our lives (Jer. 29:11). And to that plan, or to that end, He will always remain faithful.
Imagine a blacksmith, making a sword. He has a plan, knowing exactly what kind of sword he is making. He begins by plunging a raw piece of metal into a furnace. It remains in there until the instant the smith knows it is ready. Then, out it comes and immediately, the smith begins pounding it with a hammer. Then, after the precise number of blows, into the water it goes, only to be returned to the fire yet again.
This does not sound comfortable from the point of view of the piece of metal. Yet the blacksmith knows exactly what he is making and will continue to do everything necessary until that raw piece of metal becomes a finely-honed sword. That blacksmith remains faithful to the end throughout the whole process, keeping the plan for the finished sword in mind the whole time.
In much the same way, God is taking these raw lumps of metal called "you and I" and He is forming something wonderful with us. He has a plan in mind; He knows what He is making us into. And He is willing to do what it takes to form us. Even if it means plunging us into the fires of adversity or striking us with the hammer of trials. He knows exactly what it needed, no more and no less, to form in us what He has purposed.
And I dare say that it is precisely because He is working in us to produce His plan for us that we can ultimately and entirely trust Him. Because we know that He is in control and that He will work all things together for our good (Rom 8:28), we can yield to His process. We can put our trust in Him, even through the trials and adversities we face, knowing that God is at work producing something beautiful in our lives and knowing that He will do exactly and ONLY what is needed to accomplish His purpose.
Yes, God is always faithful. ALWAYS faithful to the end!
