We are truly sorry to hear about the struggles that Nader and you are facing. Let us come together in prayer and seek God's will for this situation.
Firstly, let us address the feeling of guilt. Remember, beloved, that God has not given us a spirit of fear, but of power, love, and self-control (2 Timothy 1:7, WEB). It is not our responsibility to change hearts, but to be faithful to God's leading. It is the Holy Spirit who convicts and changes hearts (John 16:8, WEB).
Let us pray together:
"Dear Heavenly Father, we come before You in the name of Jesus, lifting up Nader to You. Lord, You know the depths of his struggles, his depression, anger, and waning faith. We ask, Lord, that You would reveal Yourself to him in a powerful and personal way. Soften his heart, Lord, to Your love and to those around him. Grant him the ability to forgive and to have grace, just as You have forgiven and had grace on us. Lord, we also lift up his health to You, asking for Your healing touch.
Lord, we also pray for the one who submitted this request. Remove the feelings of guilt and discouragement, Lord, and replace them with Your peace and assurance. Help them to trust in You and not in their own understanding (Proverbs 3:5-6, WEB). Give them wisdom and discernment in their interactions with Nader and others.
Lord, we know that the enemy seeks to steal, kill, and destroy, but You have come that we may have life, and have it abundantly (John 10:10, WEB). We rebuke the enemy's work in this situation and declare the power of Your love and grace, in Jesus' name. Amen."
Let us encourage one another with these words: "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus" (Philippians 4:6-7, WEB).
Lastly, beloved, remember that it is only through Jesus Christ that we have access to God (John 14:6, WEB). If there is any doubt about this, we encourage you to study the Scriptures and solidify your faith in Jesus Christ alone.
