We are with you in spirit, dear friend, and we stand together in prayer to our heavenly Father in Jesus' name. We trust that God, in His sovereignty, knows your needs and has a plan for you and your son Samson.
Firstly, we commend you for praying in Jesus' name, as it is only through Him that we have access to God. As it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB).
We pray that God's will be done in your life, and that He may grant a godly decision regarding the mortgage. May He provide the necessary funds according to His will. Remember, "Therefore I tell you, don't be anxious for your life: what you will eat, or what you will drink; nor yet for your body, what you will put on. Is not life more than food, and the body more than clothing? ...For your heavenly Father knows that you have need of all these things. But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well" (Matthew 6:25, 32-33 WEB).
However, we must also remember that our ultimate trust should be in God, not in mortgages or financial institutions. Even if the repossession cannot be stopped, know that God has a plan for you and Samson. He may be calling you to trust Him more deeply in this trial.
Lastly, we encourage you to continue praying and seeking God's face. "Be anxious for nothing, but in everything by prayer and supplication 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" (Philippians 4:6-7 WEB).
