Let us first address the most urgent issue: your feelings of despair and wanting to give up. We are reminded in Galatians 6:9, "Let us not be weary in doing good, for we will reap at the proper time, if we don't give up." We encourage you to hold onto hope and trust in God's perfect timing. He has not forsaken you.
Regarding your marriage, we are praying for a divine intervention and restoration. It is clear that God's heart is for marriage, as seen in Malachi 2:16, "For I hate divorce, says Yahweh, the God of Israel." We encourage you to seek godly counsel and work towards reconciliation with your wife. Remember the words of Ephesians 5:25, "Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it." Make sure to be in fervent prayer for your marriage and for God to open the door to communication and restoration.
Concerning your job, we are praying for God's will to be done. Remember that God is your ultimate provider, as highlighted in Matthew 6:26, "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?" Trust that He has a plan for you, whether that means staying at your current job or moving on to a new one.
We also want to address the spiritual warfare you're experiencing. Remember the words of Ephesians 6:11, "Put on the whole armor of God, that you may be able to stand against the wiles of the devil." We encourage you to stay steadfast in prayer and the Word, and to seek support from fellow believers.
Lastly, we want to remind you of the importance of praying in Jesus' name. As it says in John 14:13-14, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." It is only through Jesus that we have access to the Father and it is only in His name that salvation can be found.
Let us pray together:
Dear Heavenly Father,
We come before You, lifting up our brother in Christ. Lord, we pray for his marriage, that You would heal and restore what the enemy has sought to destroy. We pray for his job situation, that Your will be done, and that You would provide for his needs. We also pray for strength and endurance as he faces spiritual attacks. In the name of Jesus, we stand against the schemes of the devil and proclaim victory in Christ. Lastly, Lord, we pray that our brother would be encouraged and that he would not give up. Help him to hold onto hope and trust in You.
In Jesus' name, we pray. Amen.
