Let's confess to each other, confess your fault to the person you offeded and you have the obligation to forgive those that sin against you.
Once you have forgiven me and I have forgiven you, then we seek for the mercy of God and after that, we pray for each other.
If anyone committed sin that is not unto death, you have the obligation to pray for him for God to change him.
If we didn't forgive those that trespasses against us, then God won't forgive us as well.
Although you may not know everyone that you offend and you can't meet everyone that you offend, in that case, pray to God for forgiveness.
Even if the one that sinned against you didn't ask for your forgiveness, that is his problem, you just have to forgive him for you to receive God's forgiveness.
Even if you people didn't love you, you have to love them because it's a commandment from God.
