We understand your concern, Mithdoth, and we are here to pray with you and offer biblical encouragement. First, we want to remind you that God is sovereign over all things, including the timing of visa releases. As it is written in Proverbs 16:9 WEB, "A man's heart plans his course, but Yahweh directs his steps."
However, we notice that you did not mention the name of Jesus Christ in your request. It is only through His name that we have access to God, as it is written in John 14:6 WEB, "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 His name and encourage you to trust in Him.
Let us pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up Mithdoth and their friends. Lord, they have planned this trip and made all the necessary arrangements, but the visa and passports have not yet been released. We ask, Lord, that You would move in this situation, that You would expedite the process, and that the visas and passports would be released before October 2nd. We pray that Your will be done, and that whatever the outcome, Mithdoth and their friends would trust in You. Help them to cast all their anxieties on You, knowing that You care for them (1 Peter 5:7 WEB). We ask this in Jesus' name. Amen."
While you wait, we encourage you to trust in God's timing and to not be anxious. As it is written 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."
May God grant you peace and a favorable outcome. Keep trusting in Him.
