The word "invited" (in the neuvangel)

The word "invited" means that someone is doing the inviting, and that one is the Judge who is being asked when he will avenge the blood of his servants on us (Rev. 6:10). Since he will avenge their blood (Rev. 19:2) when the bloodshed has stopped (Rev. 6:11), it is merciful of him to invite Christians to participate in stopping the bloodshed, so that Christians can have a chance to be clear from the blood of the victims.
