Hi mercedes12, and welcome to Oasis. So glad you are here.
We have an enemy, such has been said here, who is in a battle for our souls. In addition to whats already been said here, I would encourage you to pray...pray..and pray some more for your brother. He is in need of Jesus, as we all are. God can and does overcome anything He wills. Pray for him. Intercede for him.
Im praying for you, your family and for your brother.
In Jesus,
love momo
p.s. Im being led to share this with you...a pastor I had one time was one of the most loving God-fearing men I knew. God's love radiated from this man's heart. As a child, he was abused. His mother had been a high-priestess in satanism..she hated the very name of God. He grew in the Lord as she grew further and further away. His heart ached for her soul. He prayed, prayed, lamented, prayed, fasted...for years..and years, as the Lord led. In her older years, the Lord reached her..healed her, and saved her.
Please be encouraged..intercede for him. God bless you.
