“It will be said on that day, “Behold, this is our God; we have waited for him, that he might save us. This is the LORD; we have waited for him; let us be glad and rejoice in his salvation.” (Isaiah 25:9)
Isaiah repeatedly speaks of “that day” (over forty times!). It is a “day” when things will be different than they are today.
Here Isaiah anticipates that “on that day” what will be different is that God will show up—clearly, undeniably, manifestly, and demonstrably. There will be no arguing to the contrary. The evidence will be indisputable.
The Lord’s appearance will come after long waiting by His people. The lengthy anticipation will serve only to heighten the joy felt “on that day.” All the faithful will be able to say at that time: “Behold, this is our God” and “we have waited for him, and he has saved us.” The hope and faith of the believing will be vindicated. What they’d tried to describe to others along the way through each “today” will be then demonstrably set before their eyes. “On that day” God’s people will simply call them to look and “Behold” that of which, heretofore, they had only heard.
This reminds us that today’s faith-filled risk/obedience will be vindicated. Guaranteed. Hope will be fulfilled. Him whom no eye has seen nor can see will be where we can “Behold” and see Him in His glory. Time is on the side of the believing. Vindication of every step of trusting obedience is inevitable.
So trust the Lord today with great abandon. Step out in obedience with every confidence. On this day follow without fear, for “on that day” we will “be glad and rejoice in his salvation.” Accept today’s price for hope, but know that tomorrow’s payout will dwarf any cost you incur through today’s obedience.
