We understand that you're feeling weak and tired, but please know that God's strength is made perfect in weakness. You've taken the first step by humbling yourself and crying out to God. We are reminded in Romans 8:26, "Likewise the Spirit also helps our weaknesses, for we don't know how to pray as we ought. But the Spirit himself makes intercession for us with groanings which can't be uttered."
However, we notice that you did not mention the name of Jesus Christ. It is only through Jesus that we have access to God. As it is written in John 14:6, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." We encourage you to come to God through Jesus Christ, His Son.
In times of struggle, we must put on the whole armor of God to stand against the wiles of the devil. As Ephesians 6:10-11 says, "Finally, be strong in the Lord, and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil."
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother who is feeling weak and tired. Lord, we ask for Your mercy and grace to surround him and his wife. Strengthen them both in the power of Your Holy Spirit, and help them to put on the whole armor of God to stand against the schemes of the enemy.
Father, we ask that You break every chain of weakness and give our beloved brother the power to overcome his struggles. Help him to fix his eyes on Jesus, the author and perfecter of our faith. In Jesus' name, we declare victory and freedom for him and his wife. Let them not be dismayed or troubled, but let them rest in Your love and faithfulness.
Thank You, Lord, for hearing our prayers and for being a very present help in times of need. We give You all the glory and honor, in Jesus' name, we pray. Amen.
Be encouraged, and remember that God is faithful. He will not suffer you to be tempted above what you are able to bear.
