When Jesus reassured Martha that “Your brother will rise again,” (vs. 23) she expressed hope of all believers, saying, “I know that he will rise again in the resurrection on the last day” (vs. 24).
But Jesus’ wasn’t just saying that there would be a resurrection (there will be!), but that He IS the resurrection.
Jesus is the personal power and cause of it. He’s the life-giver unto everlasting life. Jesus had power over His own life and death, as He said, “I lay down My life so that I may take it again” (Jn 10:17). And He has the power to give life to others. “For just as the Father raises the dead and gives them life, even so the Son also gives life to whom He wishes” (Jn 5:21).
So Jesus clearly announced to Martha, a believer so recently affected by death, “I am the resurrection and the life; he who believes in Me will live even if he dies, and everyone who lives and believes in Me will never die” (vss. 25,26). These are bold, bold claims. But believing these things is what makes us believers. So He directly asked her, “Do you believe this?” (vs. 26).
Let our answer always be as clear as hers was—as one who knew both death and Jesus personally—“Yes, Lord; I have believed that You are the Christ, the Son of God, even He who comes into the world.” (vs. 27).
