John 4:46-54So he came again to Cana in Galilee, where he had made the water wine. And at Capernaum there was an official whose son was ill. 47 When this man heard that Jesus had come from Judea to Galilee, he went to him and asked him to come down and heal his son, for he was at the point of death. 48 So Jesus said to him, “Unless you [plural] see signs and wonders you will not believe.” 49 The official said to him, “Sir, come down before my child dies.” 50 Jesus said to him, “Go; your son will live.” The man believed the word that Jesus spoke to him and went on his way.
51 As he was going down, his servants [bondservants] met him and told him that his son was recovering. 52 So he asked them the hour when he began to get better, and they said to him, “Yesterday at the seventh hour the fever left him.” 53 The father knew that was the hour when Jesus had said to him, “Your son will live.” And he himself believed, and all his household. 54 This was now the second sign that Jesus did when he had come from Judea to Galilee.
So many times, in the Bible Study, "Anointed, Transformed, Redeemed" (Priscilla Shirer, Beth Moore, Kay Arthur) - David records asking the Lord what he should do. What is striking about David is this, he does what the LORD says he should do. Because, more importantly, David believed God and acted in faith.
just as Abraham “believed God, and it was counted to him as righteousness”
Now faith is the assurance of things hoped for, the conviction of things not seen.
When he entered the house, the blind men came to him, and Jesus said to them, “Do you believe that I am able to do this?” They said to him, “Yes, Lord.”
And Jesus, perceiving in himself that power had gone out from him, immediately turned about in the crowd and said, “Who touched my garments?”
All things are possible to him who believes
