'Deserving' in the Bible

Concerning unmarried women I have no command to give you from the Lord; but I offer you my opinion, which is that of a man who, through the Lord's mercy, is deserving of your confidence.

If others receive this right from you, are we not more deserving? But we have not made use of this right. Instead we endure everything so that we may not be a hindrance to the gospel of Christ.

For I am the least [worthy] of the apostles, and not fit to be called an apostle, because I [at one time] fiercely oppressed and violently persecuted the church of God.
