'Religion' in the Bible

With the knowledge that the law is made, not for the upright man, but for those who have no respect for law and order, for evil men and sinners, for the unholy and those who have no religion, for those who put their fathers or mothers to death, for takers of life,

And we all agree, our religion contains amazing revelation: He was revealed in the flesh, vindicated by the Spirit, seen by angels, proclaimed among Gentiles, believed on in the world, taken up in glory.

But have nothing to do with unclean and foolish stories. Give yourself training in religion:

For the training of the body is of profit for a little, but religion is of profit in every way, giving hope for the life which now is, and for that which is to come.

But if any widow has children or grandchildren, they must learn to practice godliness toward their own family first and to repay their parents, for this pleases God.

If any man gives different teaching, not in agreement with the true words of our Lord Jesus Christ, and with the teaching which is in agreement with true religion,

But you, O man of God, keep yourself from these things, and go after righteousness, religion, faith, love, a quiet mind, gentle behaviour.
