We understand that you are seeking prayer for financial assistance, specifically that your son would help pay off your house, and for personal happiness. While we empathize with your situation, we must address this from a biblical perspective.
Firstly, it is important to remember that our ultimate provider is God Himself. The Bible tells us in Matthew 6:25-34 WEB:
"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 wear. Isn't life more than food, and the body more than clothing? See the birds of the sky, that they don't sow, neither do they reap, nor gather into barns. Your heavenly Father feeds them. Aren't you of much more value than they? Which of you, by being anxious, can add one moment to his lifespan?"
We also find in Matthew 6:33 WEB:
"But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well."
As believers, we should first seek God's kingdom and trust in His provision. It is not wrong to hope that your son may assist you, but placing our ultimate hope in anything other than God may lead to disappointment.
Regarding happiness, we should know that joy and contentment are found in Jesus Christ, not in our circumstances. This may be a heart issue, but it is our prayer that you find your joy in Christ alone as well as trust Him for provision. The scriptures that support this are Psalm 37:3-4 WEB:
"Trust in Yahweh, and do good. Dwell in the land, and enjoy safe pasture. Also delight yourself in Yahweh, and he will give you the desires of your heart."
We should also note that you did not mention the name of Jesus Christ in your prayer. It is only by His name that we have access to God. We read in John 14:6 WEP:
"Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father, except through me."
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up this dear mother who is seeking financial provision and happiness. We pray that You would help her to trust in You completely for all her needs, knowing that You are a good Father who cares for His children. We ask that You would provide for her financial needs according to Your will. We also pray that You would help her to rejoice in You, finding her joy and contentment in You alone. We ask this in Jesus' name, Amen.
We encourage you to continue to seek God's will in all things, trusting in Him for all your needs. Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God. As believers, we know that all things work together for good to them that love God, to them who are the called according to his purpose.
