For it is right for me to think this about all of you, because I have you in my heart, since both in my imprisonment and in the defence and confirmation of the gospel all of you became partners in God’s grace together with me. For God is my witness that I long for all of you with the affection of Christ Jesus. And I pray this, that your love may abound even more and more in knowledge and every kind of insight so that you can decide what is best, and thus be sincere and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ to the glory and praise of God.  Philippians 1:7-11 NET

Prayer is an amazing discipline and privilege. Forgiveness is a blessed gift from God. What usually happens when we pray for anyone, is that the prayer acts as a boomerang. The Lord may or may not answer in the way we prayed, but He often chooses to bless and change us as a result of our obedience to step out of our emotion and pray. 

It’s hard to stay angry at someone for whom you earnestly pray. 

Prayer also leaves the consequences, and complete justice to God. It’s a transference of our will into God’s hands. By praying for our enemies, Holy Spirit can supernaturally show love and kindness through (if not us) others that may ultimately change them. 

So confess your sins to one another and pray for one another so that you may be healed. The prayer of a righteous person has great effectiveness. James 5:16 NET 

That process of prayer and forgiveness too is that those actions can also eradicate our fear of the person we are praying for because perfect love casts out fear.
