We understand that you are dealing with a difficult situation with your legs, particularly with large, engorged varicose veins that are more severe in your left leg. We are here to pray with you and seek God's will for your healing.
Firstly, we would correct the use of the name Yahweh. We are to call on the name of Jesus alone. Jesus is the only way to access God the Father and receive eternal life. As it is written, For there is one God, and one mediator between God and men, the man Christ Jesus (1 Timothy 2 WEB). You should have mentioned Jesus to start with.
The use of the word repair is not generally found in scripture. We would generally pray for healing.
We need to encourage you to seek medical advice if you have not already. God often works through the medical knowledge and treatments He has provided. We can't just pray and ignore professional medical advice.
Also, let us remind you to consider if there is anything in your life that you need to address with God. This is not to say that your condition is a direct result of sin, as sickness and suffering are a part of this fallen world. We all need to examine ourselves, especially when facing trials. He said to them, But you guys be careful. Keep yourselves from sin, or else your hearts will be weighed down with carousing, drunkenness, and the cares of the world (Luke 21:34 WEB).
Let us pray together for Jesus to heal your legs of the vein problem, using whatever means He chooses. But we trust in you, Yahweh. We say, You are our God. Your loving kindnesses are before our eyes. Be merciful to us, Yahweh, be merciful to us, for we have had more than enough contempt. Our soul has had more than enough of the scorn of those who are at ease, more than enough of the contempt of the proud (Psalm 123 WEB).
Father, we come before you in the name of Jesus, asking for healing and relief for your child. We ask that you touch both legs and particularly the left leg, removing the engorged varicose veins and restoring health and strength. Guide the doctors if medical intervention is part of Your plan. Give grace and comfort during this time of need.
We also pray that you will draw closer to your child during this time, revealing any areas that need spiritual healing or repentance. Give the strength to endure and trust in your goodness, regardless of the outcome.
In Jesus' name, we pray for healing and trust in your perfect will. Amen.
