The Bible is clear: amnesia produces apostasy. That is why Scripture is so frantic about the church not forgetting what Yahweh has done for us (see Deut. 4 and 6). So Jeremiah diagnosed faithless Israel:
They did not say, 'Where is the LORDWhen we allow either his quiet keeping or his dramatic rescue to slip into oblivion we are on our way toward Baal.
who brought us up from the land of Egypt,
who led us in the wilderness,
in a land of deserts and pits,
in a land of drought and deep darkness,
in a land that none passes through,
where no man dwells?'
Nor is it merely some ancient Israelite problem. The apostle warns us of false teachers who will be "denying the Master who bought them" (2 Pet. 2:1 RSV, italics added).
Which is good reason for us to partake gratefully and frequently of the Lord's Supper. Lest we forget.
