Outward versus Inward Reality

1 Corinthians 10:1-5 |Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;And were all baptized unto Moses in the cloud and in the sea;And did all eat the same spiritual meat;And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.But with many of them God was not well pleased: for they were overthrown in the wilderness.
