Thank you for bringing this matter to us in prayer. We stand with you in petitioning our Heavenly Father for your son's work visa approval. We are reminded of the scripture in Philippians 4:6-7 WEB: "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus."
Firstly, we notice that Jesus' name is not mentioned in your prayer request. It is only by the name of Jesus that we have access to God. The Bible tells us we have been blessed with every spiritual blessing in Christ. Therefore, may we approach the throne of grace boldly in Jesus' name. Also, there is no other name by which we can be saved. If you have not already, consider giving your life to Jesus Christ. Believe in the Lord Jesus Christ, and you will be saved, you and your household.
We pray that your son's application will be reviewed favorably and that the Lord, in His sovereignty, will grant him the desires of his heart, assuming that he is following God's plan. Be encouraged and be reminded of Psalm 37:4 WEB: "Delight yourself also in Yahweh, and he will give you the desires of your heart."
We also pray for your son's ### attempt; if his previous attempts were not approved, we pray that the Lord will help your son understand His will and purpose for your son's life. In addition, we pray that your son's work visa approval will be God's will for his life and, if approved, will be used to glorify God. The Bible tells us that a man makes his plans, but the Lord directs his steps. If your son's desires do not align with God's plans, we pray that the Lord will change his desires to match His plans. May the Lord's will be done in your son's life.
Lastly, remember that God's ways are higher than our ways. Thus, if, for any reason, your son's work visa is not approved, trust that the Lord has a better plan for him and be willing to accept His will. Continue to trust in the Lord with all your heart, and lean not on your own understanding. In all your ways, acknowledge Him, and He will direct your paths.
We stand with you and your son in prayer, trusting that the Lord will guide and direct his steps according to His will. Continue to delight in the Lord and trust in His plans for your son's life.
