We are glad that you have reached out, seeking God's will for your life. It is only in Jesus' name that we can approach God the Father, and it is commendable that you have acknowledged this in your request. Remember, God does not cause evil, but He does allow trials and tribulations to strengthen our faith and draw us closer to Him. As the WEB says in James 1:2-4, "Count it all joy, my brothers, when you fall into various temptations, knowing that the testing of your faith produces endurance. Let endurance have its perfect work, that you may be perfect and complete, lacking in nothing."
Firstly, we want to address the mistreatment you've endured. It is not God's will for you to remain in a situation where you are being harmed or abused. God calls us to love and respect one another, and enduring abuse is not a sign of longsuffering, but rather a sign that boundaries need to be set. As it is written in Romans 12:18, "If it is possible, as much as it is up to you, be at peace with all men." This means we should strive for peace, but sometimes it is not possible to find it if others do not share the same motives. We should never accept to be in a situation of abuse. We should rebuke and remove ourselves from it if necessary. You may consider involving others of authority to help remove yourself from such a situation.
Regarding your living situation and life's purpose, know that God has a plan for you. As Jeremiah 29:11 states, "'For I know the plans that I have for you,' says Yahweh. 'Plans for peace, and not for evil, to give you hope and a future.'" Trust that He will reveal His will for you in His perfect timing. Seek Him daily through prayer and reading His Word. As you draw near to Him, He will draw near to you.
Let us pray together:
Heavenly Father, in the name of Jesus Christ, we lift up our brother to You. We thank You for his faith and trust in Your will for his life. Reveal Your purpose to him, Lord, and guide him to the place where You would have him live. Heal his heart from the mistreatment he has endured, and give him the strength to set boundaries and remove himself from harm. Let him be surrounded by a Christian community that will love, support, and encourage him as You do. Teach him to be strong in Your strength and to believe that You will provide for him. In Jesus' name, we pray. Amen.
Be encouraged, and remember that God loves you more than you can imagine. He is always with you, and He will never forsake you. Keep trusting in Him, and He will direct your paths.
