Scripture John 4: 43-54
43 After the two days he went out from there and went into Galilee. 44 For Yeshua himself testified that a prophet has no honour in his own country. 45 So when he came into Galilee, the Galileans received him, having seen all the things that he did in Jerusalem at the feast, for they also went to the feast. 46 Yeshua came therefore again to Cana of Galilee, where he made the water into wine. There was a certain nobleman whose son was sick at Capernaum. 47 When he heard that Yeshua had come out of Judea into Galilee, he went to him, and begged him that he would come down and heal his son, for he was at the point of death. 48 Yeshua therefore said to him, “Unless you see signs and wonders, you will in no way believe.”
49 The nobleman said to him, “Sir, come down before my child dies.” 50 Yeshua said to him, “Go your way. Your son lives.” The man believed the word that Yeshua spoke to him, and he went his way. 51 As he was now going down, his servants met him and reported, saying “Your child lives!” 52 So he enquired of them the hour when he began to get better. They said therefore to him, “Yesterday at the seventh hour, the fever left him.” 53 So the father knew that it was at that hour in which Yeshua said to him, “Your son lives.” He believed, as did his whole house. 54 This is again the second sign that Yeshua did, having come out of Judea into Galilee.
John tells us that the nobleman believed Jesus had healed his son, and started his journey home. To trust that what we ask for, we will receive, can be hard to do. We, like the people of Jesus' day, want proof. We look for some sign (in many ways like a receipt for an item purchased) to show us that we will get it. When we don’t (or it doesn't come fast enough) then, we are tempted to think asking is waste of time, or that it is not coming. When you think like this, remember the nobleman and his son.
