What is Godliness?

Godliness - transliterated from Hebrew: eusebeia

1 Tim 6:3-6
If anyone advocates a different doctrine and does not agree with sound words, those of our Lord Jesus Christ, and with the doctrine conforming to godliness, he is conceited {and} understands nothing; but he has a morbid interest in controversial questions and disputes about words, out of which arise envy, strife, abusive language, evil suspicions, and constant friction between men of depraved mind and deprived of the truth, who suppose that godliness is a means of gain. But godliness {actually} is a means of great gain when accompanied by contentment.

1 Tim 3:11
But flee from these things, you man of God, and pursue righteousness, godliness, faith, love, perseverance {and} gentleness.
It is separate from righteousness.

1 Tim 3:16
By common confession, great is the mystery of godliness: He who was revealed in the flesh, Was vindicated in the Spirit, Seen by angels, Proclaimed among the nations, Believed on in the world, Taken up in glory.
It is the gospel, played out in our lives.

Acts 3:12
(same word: eusebeia)
But when Peter saw {this,} he replied to the people, "Men of Israel, why are you amazed at this, or why do you gaze at us, as if by our own power or piety we had made him walk?
It is piety, or the act of revering God.

Acts 10:12
(same word: eusebeia)
a devout man and one who feared God with all his household, and gave many alms to the {Jewish} people and prayed to God continually.
It is the act of being devout.

From 1 tim 6:3-6, we can be devout/pious/Godly, but without contentment, it is something to be despised! But with contentment, it is great gain! Question is... how do we get that contentment?

I say it's from the cross (1 tim 3:16). It is the gospel! Christ died for our sins. He has given us a gift that, number one, is undeserved, and, number two, could not be acquired without him. I can be content with only food and covering (later in 1 tim 6:7) because Christ was content with death! Praise the Lord for his mercy towards me, the sinner, transgressor of his law.
