“Hear me when I call, O God of my righteousness: thou hast enlarged me when I was in distress; have mercy upon me, and hear my prayer.”
Psalms 4:1 KJV
Thus saith the Lord, “Call unto Me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.”
So I have called upon Thee, for thou wilt hear me, O God: incline thine ear unto me, and hear my speech. Shew thy marvellous lovingkindness, O Thou that savest by thy right hand them which put their trust in Thee.
Give thanks unto the Lord , call upon his name, make known his deeds among the people.
1 Chronicles 16:8 KJV
Seek ye the Lord while he may be found, call ye upon him while he is near:
Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the Lord , and he will have mercy upon him; and to our God, for he will abundantly pardon.
Isaiah 55:6-7 KJV
For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
For whosoever shall call upon the name of the Lord shall be saved.
How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
So then faith cometh by hearing, and hearing by the word of God.
Romans 10:12-17 KJV
