Psalm 145:18

The Lord [is] nigh unto all them that call upon him
He is not only nigh unto them in relation, being their near kinsman, brother, father, husband, and head, but with respect to place and presence; not in a general way, as he is the omnipresent God, and so nigh to all, and from whose presence there is no fleeing; but in a special way, he is so nigh to them as he is not unto others, ( Deuteronomy 4:7 ) . He is in their hearts, and dwells there by faith, and they dwell in him; his blood is sprinkled in their consciences, and his righteousness is unto them and upon them; his salvation is brought near to them, to their very hearts, and they are nearer that than when they first believed; he is nigh to them that call upon him, for Christ is equally called upon as the Father; see ( 1 Corinthians 1:2 ) ( Acts 7:57 ) ( 22:16 ) ; so as to give them what they ask of him, and to help them in all their times of need; to all that call upon him in truth;
in faith and with fervency, constantly and importunely, and in the sincerity and uprightness of their hearts; with true hearts, cordially and affectionately; their hearts and mouths agreeing together, as Kimchi observes.
