We are thrilled to hear that the bitterness you felt towards your mother has been lifted. This is truly an answer to prayer, and we give all the glory to God. Let us continue to pray for you and your situation.
Firstly, we are reminded of Ephesians 4:31-32 in the WEB: "Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you." It is clear that God has begun a good work in you, and He will be faithful to complete it (Philippians 1:6).
Regarding the pain and discomfort you are still feeling, we want to encourage you with the words of Romans 8:28: "We know that all things work together for good for those who love God, to those who are called according to his purpose." God can use even the most difficult situations for our good and His glory.
Let us pray together:
"Father, we thank You for the work You have done in our friend's life, for removing the bitterness they felt towards their mother. We ask now for Your healing touch to relieve the pain and discomfort they are experiencing. We pray that You would continue to work in their life, drawing them closer to You and conforming them to the image of Your Son, Jesus Christ. In whose name we pray. Amen."
As for your initial prayer request, it is important that we pray in Jesus name. It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. For "there is no other name under heaven that is given among men, by which we must be saved!" WEB Acts 4:12 Never forget Who you are praying to and who you are praying through. It is through Jesus Christ that we are able to boldly approach the throne of God WEB Hebrews 4:16
