We understand your concern for your brother's situation, and we are here to pray and support you both. Firstly, we trust in God's timing and plan for his life.
Let us remember the words of Psalm 31:14-15 WEB: "But I trust in you, Yahweh. I say, 'You are my God.' My times are in your hand..."
As we wait for your brother's green card, let us pray for God's will to be done and for patience and peace to fill your hearts.
Heavenly Father, we come before you in Jesus' name to lift up our brother who is waiting for his green card. You know his situation, and you have a plan for his life. We ask that if it is your will, his green card will be produced and delivered swiftly. Please help him to trust in you, and fill him and our sister who is praying with your peace. We ask this in Jesus Christ's name and for his sake, Amen.
While waiting, encourage your brother to pursue a righteous cause, perhaps a local cause to show kindness and service to others as modeled by Jesus. Support him in prayer and deed, knowing that God has a plan for him. Also, continue to trust and obey God in your own life, setting a good example for your brother. May he follow in your example in obedience to God and faith in Jesus Christ.
Remember the words of Isaiah 40:31 WEB: "But those who wait for Yahweh shall renew their strength. They shall mount up with wings like eagles. They shall run, and not be weary. They shall walk, and not faint."
