'Freely' in the Bible

Since we have such a [glorious] hope and confident expectation, we speak with great courage,

Our mouth has spoken freely to you, O Corinthians, our heart is opened wide.

How while they were undergoing every sort of trouble, and were in the greatest need, they took all the greater joy in being able to give freely to the needs of others.

For even though I boast rather freely about the authority the Lord gave us for building you up and not for destroying you, I will not be ashamed [of the truth],

Have I committed an offence in abasing myself that ye might be exalted, because I have preached to you the gospel of God freely?
