The “day” (3117) of “wrath” (5678) is assumed to be judgement day. At least I assume that is what it means. If that is true then again this is consistent with the teaching of the rest of the Bible. If we are believers, living in “righteousness” (6666), then we do not live in fear of the wrath of God. Jesus talked about this right after the well known John 3:16.
(John 3:18 KJV) He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.I think that there is often a way in which righteousness protects of from wrath on a daily basis. I think of how often I have been standing in class simply looking at a student and he will cry out, “I didn’t do it!” Since I often have no idea what he is feeling guilty about I will ask, “Then who did?” Sometimes it works. The point is that they are living in fear of wrath because they know they are guilty.
So? We don’t need to live that way. Every time there is a terrorist attack the kids will ask me if I am afraid. I tell them no, I am ready to go. I feel that way when I am flying and the plane does something funny. It is a state of mind created by knowing I am covered by the blood.
