The mouth of God's servant

"Then the woman said to Elijah, 'Now by this I know that you are a man of God, and that the word of the Lord in your mouth is the truth.'” 1 Kings 17.24

The cry of a desperate mother was answered. Her son was raised from the dead by a word spoken by the prophet. Her immediate reaction was to recognize that the Word of God in the mouth of His servants is true. There you see one more difference between those who serve the Almighty and those who serve Him not.

The outcry

"This poor man cried out, and the Lord heard him, and saved him out of all his troubles." Psalms 34.6

The poor man from this passage was the Psalmist himself. He cried and was heard, not because he deserved, but because of the faith in the compassion of the Almighty, expressed through his outcry.
That's how it works: God does not take into account the degree of the sin one commits, nor its amount, much less professed religion, but a sincere expression of faith in His Word.

CRY OUT

"I will lift up my eyes to the hills—from whence comes my help? My help comes from the Lord, who made heaven and earth."   Psalm 121:1-2

Only those who have a commitment with God the Son can cry out to God the Father with certainty that they will be heard.
This conviction is revealed by God the Holy Spirit to His children.
