Because they have been blinded to The Truth. Reality is something they cannot see and will never be a part of. Christians are thankful for one another because we have been chosen through sanctification to believe The Truth.
Obviously at the time of birth we had not been sanctified and were unregenerate heathens filled with evil and deserving of torture. Torture forever. Nevertheless God had chosen us and we were capable of seeing The Truth when it was presented to us. We were able to change from what we were to what we are now. They are not.
II Thessalonians 2:11-13 For this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness. But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth.
The people you refer to
cannot see Godliness, because they are deluded, not even among people in the Church and since they cannot
see Him they cannot accept His embrace.
