'Faithful' in the Bible

God [is] faithful, by whom you were called to fellowship with his Son Jesus Christ our Lord.

In this case, moreover, it is sought in stewards that one be found faithful.

Because of this, I have sent to you Timothy, who is my dear and faithful child in the Lord, who will remind you of my ways in Christ Jesus, just as I teach everywhere in every church.

Temptation has not come upon you except [what is] common to humanity. But God [is] faithful, who will not permit you to be tempted beyond what you are able, but will also make a way out together with the temptation, [so that you] may be able to endure [it].
