If we truly believe in God, then we know that He can reveal truth to anyone and anything and that no human intervention (like a vaccine) could remove us from His saving Grace. God is not a feeling and we don't need to feel Him to know the truth of Him. Lastly, God does warn us to be wary but He isn't seeking to trick any one. He never set us up to be accidentally sent to hell by getting a vaccine or writing a number on our foreheads or wearing a mask. The one true God would not and does not seek to fool His children into hell. He offers unconditional forgiveness even for sins we knowingly commit, why would we then imagine He's out to fool us or allow this kind of thing? Use discernment. Spend more time in the Bible and Prayer than in the World.
