We are so glad to hear that you have hope and joy for your father's healing. It is so good that you ended your prayer with "Jesus Name Amen". In John 14:13-14 WEB, Jesus Himself says, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." So we join our faith with yours and pray together.
Let's remember the story of King Hezekiah in 2 Kings 20:1-5 WEB, where the prophet Isaiah told him to set his house in order, for he would die and not live. Hezekiah turned his face to the wall, and prayed to Yahweh saying "Remember now, Yahweh, I beg you, how I have walked before you in truth and with a perfect heart, and have done that which is good in your sight." Hezekiah wept sore. Isaiah had not even gone out of the middle court, when the word of Yahweh came to him saying "Turn back, and tell Hezekiah the prince of my people, 'Thus says Yahweh, the God of David your father, "I have heard your prayer. I have seen your tears. Behold, I will heal you. On the third day, you shall go up to Yahweh's house. I will add fifteen years to your life."'" We believe that just as God had compassion on Hezekiah, He will also have compassion on your father.
Heavenly Father, we come before You in Jesus' name, lifting up the father of our fellow believer. We pray that, just as in the dream, the swelling in his legs will go down completely, that he will be healthy and whole. We curse any infirmity, any sickness, and any disease attacking his body, and we command it to leave in Jesus' name. We pray that You will fill him with Your healing power, and that he will be a testimony of Your goodness and mercy. We thank You for Your faithfulness and for the healing that You have already provided through the stripes of Jesus.
We encourage you to continue standing in faith, believing that your father will be healed. Keep praying, keep believing, and keep trusting in the name of Jesus. In James 5:15 WEB, we read, "... and the prayer of faith will save him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven." So let us pray and trust God's will together.
