It isn’t modern language and you would realize.
“Visit” also is not used in a modern sense.
In the sentence it translates more or less as “send for a period of time”.
“Wont” means “custom”
“As is my wont” would mean, “as is usual, or customary, for me”…
Basically, the Lord is saying that those who seek God/are chosen by God, suffer temptation/dificulties, as well as consolations/joys/religious experiences.
Therefore you can read the sentence as meaning;
“it is usual for the Lord to allow His chosen ones to experience both temptations, and consolations.”
