Even if we forgive people, it does not mean that God will forgive them. He will not forgive anyone who is not in Christ. By forgiving, we settle our own consciences- but only our own. The other party has to make his or her own peace with God through Christ if his or her conscience is to be salved. We cannot be saved unless we know we are saved.
Welcome calluna
First I would like to point out that by not forgiving others who trespass against you, you are committing a sin by not fulfilling the commandment given to you by your Lord. Jesus said to him,
"I do not say to you, up to seven times, but up to seventy times seven.Matthew 6:14-15
For if ye forgive men their trespasses, your heavenly Father will also forgive you: But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.Second we are to ask that God also forgive them for the trespasses against us. (This is not a request for forgiveness from all sins they have committed against God but against us)2 Timothy 4:16 At my first answer no man stood with me, but all men forsook me:
I pray God that it may not be laid to their charge.Acts 7:55
But Stephen, filled by the Holy Spirit, gazed into heaven. He saw God's glory, with Jesus standing at the right hand of God, and he said, 56 "Look! I see the heavens opened and the Son of Man standing at the right hand of God!" 57 Then they screamed at the top of their voices, stopped their ears, and rushed together against him. 58 They threw him out of the city and began to stone him. And the witnesses laid their robes at the feet of a young man named Saul. 59 They were stoning Stephen as he called out: "Lord Jesus, receive my spirit!" 60 Then he knelt down and cried out with a loud voice,
"Lord, do not charge them with this sin!" And saying this, he fell asleep.
Do you believe that Paul and Steven's requests were denied by God?
Nice to have you on the board Brother/Sister calluna
