'Everyone' in the Bible

Each one should remain in the condition in which he was [when he was] called.

For though I am free from all men, I have made myself a slave to everyone, so that I may win more [for Christ].

However, when all things are subjected to Him (Christ), then the Son Himself will also be subjected to the One (the Father) who put all things under Him, so that God may be all in all [manifesting His glory without any opposition, the supreme indwelling and controlling factor of life].

to be subject to such leaders [treating them with courtesy and respect], and to everyone who helps in the work and labors [for the benefit of yourselves and the church].
