"How long, O Lord, holy & true, will You refrain from judging & avenging our blood on those who dwell on the earth?" REV 6:10
Evil is ancient, not timeless. It has a shelf-life. God's vengeance is on schedule, not to seek revenge, but to avenge His martyrs.
WARNING! Taser from Tozer
"The amount of loafing practiced by the average Christian in spiritual things would ruin a concert pianist if he allowed himself to do the same thing in the field of music. The idle puttering around we see in church circles would end the career of a big league pitcher in one week."
