Isaiah 35:4–5 (ESV) … “‘Say to those who have an anxious heart, “Be strong; fear not! Behold, your God will come with vengeance, with the recompense of God. He will come and save you.’ Then the eyes of the blind shall be opened, and the ears of the deaf unstopped…”
George Mueller said, “The beginning of anxiety is the end of faith, and the beginning of faith is the end of anxiety.” For those who find themselves weak in faith, filled with hopelessness and despair, the prophet reminds us we are to be strong and of good cheer.
The reason for our strength and encouragement is that the Lord our God has promised that he is coming. He is coming to accomplish all that he has promised to do. The Lord has already delivered on the promise of Salvation. Christ is the fulfillment of that promise in His life, death, and resurrection.
However, Isaiah also tells us that the Lord has promised to come in vengeance and judgment. The letter of Revelation and the words of Jesus tell us that this future promise will one day be fulfilled as well.
Much of this world missed the first coming of the Lord our God. We must not miss His second coming for this time He comes as Judge. As a believer we are not to be filled with anxiety but faith. How will others trust in Jesus if they see doubt in us? How can the eyes and ears of others be open if we run around in a worried condition? Notice that the prophet says that “we are to say…”, in other words, we are not only to live by this promise but also we are to give this promise to others.
