The Lord is patient, for He wants everyone to repent
The Lord is not slow concerning his promise, as some count slowness; but he is patient with us, not wishing that anyone should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night; in which the heavens will pass away with a great noise, and the elements will be dissolved with fervent heat, and the earth and the works that are in it will be burned up.
