We are truly sorry to hear that you are facing ridicule and struggling with peace of mind. Remember, the Lord looks at the heart, and what is on the inside is what truly matters to Him. As it is written in 1 Samuel 16:7, "But Yahweh said to Samuel, 'Don't look on his face, or on the height of his stature, because I have rejected him; for I see not as man sees, for man looks at the outward appearance, but Yahweh looks at the heart.'"
We must also address that your prayer does not include the name of Jesus Christ. It is only through His name that we have access to God the Father, as Jesus Himself said 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.'" Therefore, we pray that you will come to a saving knowledge of Jesus Christ if you have not already, and that you will find your value and peace in Him.
Let us pray together for your situation. Father, we come before You in the name of Jesus Christ, asking that You would bring conviction to those who are ridiculing our fellow believer. We ask that You would give them a spirit of repentance and that they would come to understand the harm their words can cause. We also pray for our fellow believer, that You would grant them peace of mind and the ability to forgive those who have hurt them. Help them to see themselves through Your eyes, and to find their value and worth in You. We ask this in Jesus Christ's name.
Lastly, remember what is said in Psalm 139:14, "I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well." You are beautifully and wonderfully made by God, and His love for you is unconditional and unchanging. Find your peace and confidence in Him, and forgive those who have hurt you, that you may be released from the bondage of unforgiveness.
