Sound harsh? Well, that is exactly what the apostle Paul said,
1 Corinthians 10:1–6 (NKJV)
1 Moreover, brethren, I do not want you to be unaware that all our fathers were under the cloud, all passed through the sea, 2 all were baptized into Moses in the cloud and in the sea, 3 all ate the same spiritual food, 4 and all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ. 5 But with most of them God was not well pleased, for their bodies were scattered in the wilderness. 6 Now these things became our examples, to the intent that we should not lust after evil things as they also lusted.
What do we learn:
1 - God is God and we are not.
2 - God will never be mocked.
3 - Let God be true and every man a liar.
4 - Believe on the Lord Jesus and be saved. Don't try to hide from God in the covenant people; you will only up being an example the God will use to the glorious wrath of His holy name.
