The Greek word translated salvation there is soteria . Real biblical salvation not only includes eternal protection, but also it includes protection from all the material dangers of life right here on this earth. God has created vast numbers of gloriously powerful spiritual beings for the express purpose of protecting us and delivering us from the evils of this world - from everything from hurricanes to plane crashes, from gang violence to diseases. We see examples of what angels can do all through the Bible. And they haven't retired since then either.
Angels are at work today just like they've always been.
Several years ago in one of Israel's major wars, the enemy had their guns trained on Israeli compounds. Those guns were the finest military equipment money could buy. They had a range of at least 20 miles and were equipped with electronic gun sights for accuracy. But something very odd happened. Every time they fired those guns at the Israelis, they missed their targets, in some cases, at almost point blank range.
