'Unworthy' in the Bible

I am unworthy of all the kindness and faithfulness You have shown Your servant. Indeed, I crossed over this Jordan with my staff, and now I have become two camps.

"Indeed, I am completely unworthy -- how could I reply to you? I put my hand over my mouth to silence myself.

Incline my heart to Your testimoniesAnd not to dishonest gain and envy.

Therefore, thus says the Lord [to Jeremiah],“If you repent [and give up this mistaken attitude of despair and self-pity], then I will restore you [to a state of inner peace]So that you may stand before Me [as My obedient representative];And if you separate the precious from the worthless [examining yourself and cleansing your heart from unwarranted doubt concerning My faithfulness],You will become My spokesman.Let the people turn to you [and learn to value My values]—But you, you must not turn to them [with regard for their idolatry and wickedness].
