Grace, mercy and peace to you from God the Father and from Christ Jesus our Lord 1:2 (ERV)

I always remember you in my prayers day and night. And in these prayers I thank God for you. 1:3a (ERV)

I pray that the Lord will show mercy to the family of Onesiphorus. Many times Onesiphorus encouraged me. He was not ashamed that I was in prison. No, he was not ashamed. When he came to Rome, he looked and looked for me until he found me. I pray that the Lord Jesus will make sure Onesiphorus receives mercy from the Lord God on that Day. You know how many ways this brother helped me in Ephesus. 1:16-18 (ERV)

The first time I defended myself, no one helped me. Everyone left me. I pray that God will forgive them. 4:16 (ICB)

The Lord be with your spirit. Grace be with you. 4:22 (ESV)

Likewise I can pray: 

That grace, mercy and peace will be given to people from God the Father and from Christ Jesus our Lord. I can pray this for myself also. 

Thanking God for other Christians. 

Asking God for mercy for other Christians on that Day. 

That God will forgive those who have wronged me. 

That God is with my spirit and that His grace is with me. I can pray this for other Christians also.
