When Moses preached his final message it was recorded as the fourth book of the law. In it he says the following:
20 “When your son asks you in time to come, saying, ‘What do the testimonies and the statutes and the judgments mean which the Lord our God commanded you?’ 21 then you shall say to your son, ‘We were slaves to Pharaoh in Egypt, and the Lord brought us from Egypt with a mighty hand. 22 Moreover, the Lord showed great and distressing signs and wonders before our eyes against Egypt, Pharaoh and all his household; 23 He brought us out from there in order to bring us in, to give us the land which He had sworn to our fathers.’ 24 So the Lord commanded us to observe all these statutes, to fear the Lord our God for our good always and for our survival, as it is today. 25 It will be righteousness for us if we [h]are careful to observe all this commandment before the Lord our God, just as He commanded us.Deut. 6:20 --25
Last night I saw some Hasidim refusing to immunize their children against measles though there is now an epidemic in Brooklyn. Because they take the promises Moses gave seriously. I would argue that they are in error.
But I would argue, more strongly, that for a person or a nation to choose apostasy, to turn away from the gospel, is a far greater error and that has consequences in this life and the life to come. In this life it makes one unable to test truth, for you have chosen evil. And in the life to come the apostate has proudly chosen damnation.
Hebrews 2:1-9, NASB
2 For this reason we must pay much closer attention to [a]what we have heard, so that we do not drift away from it. 2 For if the word spoken through angels proved [b]unalterable, and every transgression and disobedience received a just [c]penalty, 3 how will we escape if we neglect so great a salvation? [d]After it was at the first spoken through the Lord, it was confirmed to us by those who heard, 4 God also testifying with them, both by signs and wonders and by various [e]miracles and by [f]gifts of the Holy Spirit according to His own will.
5 For He did not subject to angels [g]the world to come, concerning which we are speaking. 6 But one has testified somewhere, saying,
“What is man, that You remember him?
Or the son of man, that You are concerned about him?
7 “You have made him [h]for a little while lower than the angels;
You have crowned him with glory and honor,
[i]And have appointed him over the works of Your hands;
8 You have put all things in subjection under his feet.”
For in subjecting all things to him, He left nothing that is not subject to him. But now we do not yet see all things subjected to him.
9 But we do see Him who was made [j]for a little while lower than the angels, namely, Jesus, because of the suffering of death crowned with glory and honor, so that by the grace of God He might taste death for everyone
I plead you, above all, to choose Christ and the gospel.
