“When they saw him they worshiped him, but some doubted” (Matthew 28:17).
“Some doubted.” Yes, even when looking at the resurrected Christ.
What can we learn from this? We can learn that while we are still in this world—even if we were to see Jesus with our own eyes—we sometimes struggle with doubt. If this was difficult for the disciples who stood staring right at Jesus, how much more necessary is it for us today!
I came across a helpful discussion of this mingling of faith and doubt in Calvin’s Institutes. I offer it here to encourage those of us who find our faith mingled with doubt—who cry with the father of the demon-possessed child, “I do believe; help me overcome my unbelief!” (Mark 9:24). (Note: I’m using Henry Beveridge’s translation. For clarity’s sake, I have updated the language and taken the liberty to paraphrase in some places).
The believer finds within himself two principles: the one filling him with delight in recognizing the divine goodness, the other filling him with bitterness under a sense of his fallen state; the one leading him to recline of the promise of the Gospel, the other alarming him by the conviction of his iniquity; the one making him exult with the anticipation of life, the other making him tremble with the fear of death. These principles are due to the imperfection of our faith. For, in this present life, we are never fully cured of the disease of distrust. We are never quite completely engulfed in perfect faith. That is why we feel those inner conflicts.
But this does not mean that faith is an obscure and confused understanding of God’s will. Even though we may be harassed by various doubts, it does not follow that we are divested of faith. Though we are agitated and carried to and fro by distrust, we are not immediately plunged into the abyss. Though we are shaken, we are not driven from our place.
The certain outcome of this struggle is this: that faith in the long run triumphs over the difficulties which try to bring it down.
Why? Because of the nature of true saving faith. As soon as the minutest particle of genuine faith is instilled into our minds, we begin to behold the face of God—in peace and favor toward us. We behold him, though far off, yet so distinctly as to assure us that there is no delusion in it.
