Matthew says, ‘he was come into the house’, without specifying which house, and he therefore expects to know he house he means. It is certainly not Matthew’s house or Jairus’ house from which he has come, so we can assume it is the house which Peter was using (Matthew 4:20), whether rented or owned.
But why does Christ insist on faith: faith in him, faith in his ability to do this miracle, faith in him to do what no other man could do? He already knew whether they believed or not, and so did not need to ask in order to find out for himself. He asked to show this is the condition of his healing power and of every blessing which we receive from God. This is about the centrality of faith. Can you exercise trust? Will you depend on Christ entirely? This is more than just making a trial of him which you half expect to go wrong. Are you absolutely certain? Will you commit yourself to him? Faith honours Christ and attributes him with the power that he does indeed possess. Faith does not give him anything that he does not already have. Faith is the bare minimum; it is his right. Anything less than faith is theft from God; it is trying to take from him what belongs to him. Just as the eye sees the light shining at it, so faith sees the glory of Christ in front of it when it rightly understands who he is. Christ had given ample evidence of who he was since his public ministry had begun, and through his words, through his miracles.
Did it require more faith on the part of these blind men to believe they would receive their sight, than it does for a lost sinner to believe that Christ will pardon his sin, give him spiritual life nd save him eternally? No. The salvation of the soul is an even greater matter than the restoration of sight, if we properly understand what is at stake. The change in the soul which the seeker asks the Lord for is just as real as the change in pgysical sight that these blind men asked for. When these men had received their sight, their own eyes would tell them they had been healed. They would look around and drink in the beauty of the scenery around them, and the converted soul sees the beauty of Christ, his love for our souls, his kindness and wisdom. It basks in his presence and longs to stay close to him who has done so much for it.
They believed even though they were blind. Let us suppose they had been blind all their lives. They had no notion of sight. How could you describe sight to someone who had never seen? The seeker says, I can’t imagine what it is like to be saved. Nor could these men imagine what it was to receive sight.. But they weren’t just being desperate, coming to Christ as a long shot. Nothing would keep them away for they believed that by being there and calling on the Lord that he would restore their sight, and so it is with the seeking soul. The miracles not only provide a picture of what Christ does for us in conversion, but they also provide a picture of how the seeking soul must respond to him.
What if we feel we do not have faith? As the seeker approaches Christ in [prayer, he may hear this challenge: ‘Believe ye that I am able to do this?’ Certainly we may ask for more faith as the man asked who ‘said with tears, Lord, I believe; help thou mine unbelief’ (Mark 9:24). But that does not release us from the need to exercise faith. We must consider who Christ is, what he has done for so many other, how many lives he has changed. We must encourage ourselves to believe by remembering the integrity of his promises, the accuracy of his prophecies, the glory of his person as revealed to us in Scripture.
