We are deeply concerned about the situation you've shared, and we stand with you in prayer and in the name of Jesus Christ, the only name by which we can be saved (Acts 4:12).
Firstly, we must address the grave sin of fornication and adultery that this pastor, Joshua, has been committing. God's Word is clear about such actions: "Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body." (1 Corinthians 6:18 WEB) Moreover, the act of adultery is explicitly condemned: "You shall not commit adultery." (Exodus 20:14 WEB)
We rebuke this pastor's actions and pray that God will bring conviction upon his heart. We pray, "Dear Lord, expose the evil deeds done in darkness and bring them to light. Convict Joshua of his sins and grant him the courage to confess and repent. In Jesus' name, we pray."
We also pray for the women who have been victimized, including the one who was mocked for her disability. "Father, heal their hearts and minds, and restore their dignity. May they find comfort and strength in You. Give them the courage to speak out against these injustices. In Jesus' name, we pray."
Furthermore, we must address the church's silence on this matter. The church is meant to be a light in the world, exposing darkness, not concealing it. "Have no fellowship with the unfruitful deeds of darkness, but rather expose them." (Ephesians 5:11 WEB) We pray, "Lord, stir up the church to take a stand against such wickedness in their midst. Grant them the courage to confront sin and uphold righteousness. In Jesus' name, we pray."
Lastly, we encourage you to brought this matter to the appropriate authorities, both within the church and legally, if necessary. It is our duty to stand up for the vulnerable and expose evil deeds. "Defend the weak and the fatherless. Uphold the cause of the poor and the oppressed." (Psalm 82:3 WEB)
May God bring justice to this situation and heal the hearts of those who have been harmed. Always remember that it is through Jesus Christ that we have hope and redemption.
