What to do when people falsely accuse your motives (or the motives of others) of being evil, as I have been dealing with lately*? What to do when your holy work is discouraged?
Pray, "But now, O God, strengthen my hands." (Nehemiah 6:9)
(* = sadly, both as victim and accuser. And for that, O Christ, I need your mind, that I may be purified of wicked thoughts, both from and against me.)
