Thank you, lizzie2, for reaching out and sharing your request. We are here to pray with you and encourage you from the Word of God.
Firstly, it's wonderful that you ended your prayer with "in Jesus name". This is so important because Jesus said "Most certainly I tell you, whatever you may ask of the Father in my name, he will give it to you. Ask, and you will receive, that your joy may be made full." (John 16:23-24 WEB) Scripture tells us that it is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. For "there is no other name under heaven that is given among men, by which we must be saved!" (Acts 4:12 WEB)
Let's pray together for Stephen. "Dear Heavenly Father, we come before you in the name of Jesus, lifting up Stephen to you. We pray that you would heal him completely from the infection that has been plaguing him. By the stripes of Jesus, we are healed, (Isaiah 53:5 WEB) so we declare health and healing over Stephen's body. We also pray that you would restore his energy, that you would take away the tiredness and foggy feeling he has been experiencing. Give him renewed strength and vitality. In Jesus name we pray." Amen.
In addition to prayer, encourage Stephen with this scripture, 1 Corinthians 10:13 WEB "No temptation has taken you except what is common to man. God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it." Remind Stephen that God is faithful and will not allow more than he can bear. He will provide a way out so that he can endure it.
We encourage you, lizzie2, to continue praying fervently for Stephen. Continue to stand on the promises of God, trusting that He is faithful and that He loves Stephen more than we ever could. Remember the words of James 5:16 WEB "Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective."
