I will pray for their blessing and not cursing. Jesus tells us to bless those who curse us, to do good to them who hurt us and to turn the other cheek, to offer it to them to slap.
We are told to , if asked for a cloak, to give two.
Romans 21: 12 SAYS, " Do not be overcome with evil, but overcome evil with good,"
It is the only way to kill it, to overpower it withthe force of goodness. I have seen this work so many times in my life. It hurts to be humble, painful at the moment, but yields great things.
I have had the Lord ask ME to apologize to people who I feel wronged me, and seen incredible healing from it, event though at the time, I did it because God forced me to. It is worth it to have peace, and power in your life.
There is no curse that can harm a child of God, who has the blood of Christ covering them. They can take your body, but never your soul.
" Lord, I ask you to bless all those who have harmed this person. Restore them to you and heal them of their wounds.
Give this person freedom from every chain!
In Jesus Name,
Amen

Brother Martin, please follow Rami's advice. Bitterness and resentment will ruin your relationship with God by hindering your prayers. And then, when the devil attacks, you will have no defense. I know this because I have lived with that bitterness for a long time and have seen it's horrible effects on my own life. So just pray for those who hurt you(I know that's very hard to do. I'm still trying to get it right), and it will protect you from satan's traps. Let nothing hinder what God has in store for you!

God bless you, brother!

Dear Lord,

Please instill forgiveness in Martin's heart and also forgive him as he has alot anger in him. Give him patience and wisdom so that he can release his anger towards the people who have harmed him in the first place. Pull Martin closer to You and let him feel Your presence again. Give him a peaceful heart. Take care of Martin and protect him from further destruction. Thank Lord. In Jesus' name, I pray.
