Devout – (adj) Yielding reverential devotion.
God used this word 9 times in Scripture: 1 time to Israel in their Koine Greek Old Testament book of Luke; 4 times to Israel in the transition book of Acts; and 4 times to the Body of Christ in the transition book of Acts.
The only instance that is devotion to God is in Israel’s Koine Greek Old Testament account.
In the 4 instances to Israel in the transition book of Acts, the devout people are devoted to their religion of Judaism.
In the 4 instances to the Body of Christ in the transition book of Acts, we see 3 instances of devout Jews, and one instance of a multitude of devout Greeks.
Today, as in Scripture, the vast majority of ‘the devout’ are devoted to their religion, not devoted to God. There are many religions to choose from, and all are vanity. The leading religion today are Christianity, Islam, Judaism.
