My son and I say prayers together each night before he goes to bed. Part of our daily prayers is the Lord's Prayer. This is the way we say it each night:
Our Father, who art in Heaven, hallowed be Thy name. Thy Kingdom come, Thy will be done, on Earth as it is in Heaven. Give us this day our daily bread, And forgive us our trespasses, ==> AS WE FORGIVE THOSE WHO TRESPASS AGAINST US. And lead us not into temptation, but deliver us from evil, for Thine is the Kingdom, and the Power, and the Glory, forever. Amen.
----- It is already in a Christian's heart to forgive those who rise up against them, and especially so when they rise up against a person because they are teaching about Jesus Christ.
In our sinful state we are expected to hate the message of God, because He testifies against our sin. But the message of God is not given for those who won't be saved, but only for those who will be saved.
This removes a huge burden from the Christian's walk. We're not responsible for converting people, but only for our obedience to God in teaching the message accurately. And we have been taught in scripture, and by life examples we've all encountered, that non-believers will rise up and attack and harm and attempt to discredit, and wreak havoc, and more, anyone who tries to bring people the message of salvation through Jesus Christ.
Nonetheless, the message goes forth because it is the Lord's guidance for us to teach. It is up to Him to bring forth the increase, and to change people from within. We are simply obedient to His call for us to go forth and teach, and to obey and live His guidance personally, as best we're able.
If you can hear His call within your heart, listen to Him. He is reaching out to save your soul from death, and to give you eternal life. Rejoice and be exceedingly glad, for your days of sorrow are ended.
