We understand that you are feeling overwhelmed and trapped, but we want to remind you that there is hope in Jesus Christ. When you said Jesus save me, we know that is the only way to be saved. Jesus is the one whom has been given all authority in heaven and in earth.
First, let's address the spiritual aspect. You reached out and asked Jesus to save you and give you a big exit door to heaven. The Bible tells us, I am the way, the truth, and the life. No one comes to the Father except through me, John 14:6 WEB. Jesus also tells us, I am the resurrection and the life. He who believes in me will still live, even if he dies, John 11:25 WEB. It is only by the name of Jesus that we have access to God. The basic Christian salvation message is to confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, and you will be saved, Romans 10:9 WEB.
It is commendable that you are trying to help your mother, but it seems that she is not taking your suggestions well. It is important to honor our parents, but it is also important to set boundaries. We are reminded in 2 Timothy 3:1-5 WEB, But know this, that in the last days, grievous times will come. For men will be lovers of self, lovers of money, boastful, arrogant, blasphemers, disobedient to parents, unthankful, unholy, without natural affection, unforgiving, slanderers, without self-control, fierce, no lovers of good, traitors, headstrong, arrogant, lovers of pleasure rather than lovers of God; holding a form of godliness, but having denied its power. Turn away from these, also. This does not mean that your mother fits all of these characteristics, but it is a reminder that we need to focus on maintaining our peace in Jesus and growing closer to him.
Regarding finances, the Bible warns us against the love of money. The love of money was a strong factor in your mother's situation. The Bible advises us as Christians against greed and the love of money. This is not saying that money is evil. Luke 16:13 WEB No servant can serve two masters, for either he will hate the one, and love the other; or else he will hold to one, and despise the other. You aren't able to serve God and Mammon.
As for your health, know that God cares about every aspect of your life, including your physical well-being. Psalm 103:2-3 WEB tells us, Bless Yahweh, my soul, Don't forget all his benefits, who forgives all your iniquities, who heals all your diseases. We are praying for your healing and for God to make a way where there seems to be no way.
Let's pray together. Father, we lift up our brother to you, asking for your divine intervention in his life. We pray for his healing, provision, and guidance. Help him to set boundaries and to trust in you. We pray that his mother will turn her heart to God and her son. We pray for him to have strength to grow closer to you through this trial. We pray for his health to improve. In the name of Jesus Christ, Amen.
Prayer Focus: God, Thank You. Thank You for loving me. God, I ask You in Jesus’ name bless me with everything that I stand in need of and everything You want me to have.
