We understand your concern and frustration in this situation, but we must remember that God calls us to trust in Him and to act with integrity even in difficult circumstances. Firstly, let's address the absence of Jesus' name in your request. It is only through the name of Jesus 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." We will pray in Jesus name for your situation.
It's important to remember that God is sovereign over all things, including our finances. As it says 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?"
However, we must also address the issue at hand. You accidentally deposited money into the wrong account, and the person has not returned it. We must consider that 1 Thessalonians 4:6 encourages us not to take advantage of others including our Christian brothers and sisters. He also tells us in Romans 13:7-8 to Give everyone what you owe him: If you owe taxes, pay taxes; if revenue, then revenue; if respect, then respect; if honour, then honour. Owe no man anything, but to love one another. Also, Romans 12:17 states "Recompense to no man evil for evil. Respect what is honourable in the sight of all men." It may be necessary to involve local authorities or legal counsel to resolve this matter fairly and justly, while also praying for a change of heart in the person who received the money.
Let us pray together:
Heavenly Father, we come before You in the name of Jesus, lifting up our brother/sister who has lost money due to an honest mistake. Lord, we ask for Your intervention in this situation. We pray that the heart of the person who received the money would be softened to return it, either directly to our brother/sister or by paying it forward to help others in need. We also pray for guidance and a successful recovery of the funds honorably and respectfully. We will give thanks to You for all you have done and will do in Jesus Name. Amen.
