No, mental conditions are not rising sharply at all. No, this does not offend God. The premise of the OP is groundless and based on fears of metal conditions or anything "weird" about anybody who does not conform to imagined ideals in society. People are
becoming more aware of how weird and different people outside their circle are and thinking others are less connected to God. Jesus had the correct approach which cannot be improved upon with freshness.
Matthew 7:12
“So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets.
Galatians 5:14
For the whole law is fulfilled in one word: “You shall love your neighbor as yourself.”
Proverbs 3:29
Do not plan evil against your neighbor, who dwells trustingly beside you.
Luke 10:27
And he answered, “You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind, and your neighbor as yourself.”
Romans 13:10
Love does no wrong to a neighbor; therefore love is the fulfilling of the law.
Matthew 19:19 s
Honor your father and mother, and, You shall love your neighbor as yourself.”
Luke 6:31
And as you wish that others would do to you, do so to them.
I worked with a guy who had Tourettes Syndrome. He was 30 and was not aware he had it until recently. Yet all those around him knew of his condition. It kind of makes finger-pointers look stupid when they criticize a mental condition the other person is not even aware of. Who is the least respectful of the two?
Take note that Jesus did not heal everyone in the world of any particular condition.
Only the handful He came in contact with.
1 Corinthians 10:24
Let no one seek his own good, but the good of his neighbor.
