We understand your concern for your son and daughter-in-law's visa approval process. Firstly, it's important to remember that God is sovereign over all things, including the hearts of kings and rulers, as it says in Proverbs 21:1, "The king's heart is in Yahweh's hand like the watercourses. He turns it wherever he desires."
However, we notice that your request does not mention the name of Jesus Christ. It is only by the name of Jesus that we have access to God, as it says in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" Therefore, we will pray in Jesus' name, as this is the only way to approach God.
Regarding your request, we will pray that if it is God's will, your son and daughter-in-law's visa would be approved. However, we also pray that through this process, they would seek God's kingdom first, as it says in Matthew 6:33, "But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well."
Let us pray:
Heavenly Father, we come before you in the name of Jesus Christ to lift up this family's needs. Lord, we ask that if it is your will, you would expedite and smooth out the process for this young couple's visa approval. We also pray that through this process, they would draw near to you and seek your kingdom first. Help them to trust in your sovereignty and goodness, regardless of the outcome. In Jesus' name, we pray. Amen.
We encourage you all to trust in God's plan, even when it is not clear to us. His ways are higher than our ways, and his thoughts higher than our thoughts, as it says in Isaiah 55:8-9.
