“And it shall come to pass that whoever calls on the name of the LORD shall be saved. For in Mount Zion and in Jerusalem there shall be deliverance, as the LORD has said, among the remnant whom the LORD calls.”
The promise began to be fulfilled on the day of Pentecost, when the Holy Spirit was poured out, and it was continued in the converting grace and miraculous gifts conferred on both Jews and Gentiles.
Calling on God supposes knowledge of Him, faith in Him, desire toward Him, dependence on Him, and, as evidence of the sincerity of all this, conscientious obedience to Him.
Whosoever shall call upon the name of the Lord – To call upon the name of the Lord, is to worship Him, as He is, depending “upon” Him. “The name of the Lord,” expresses His True Being, That which He is.
Hence, so often in Holy Scripture, people are said to “call on the Name of the Lord,” to bless the Name of the Lord, to praise the Name of the Lord, to sing praises to His Name, to make mention of His Name, to tell of His Name, to know His Name” but it is very rarely said “I will praise the Name of God” (Psalm 69:31; Hebrew), for the Name rendered “the Lord,” expresses that He is, and that He Alone is, the Self-Same, the Unchangeable; the name rendered “God” is not the special Name of God.
Hence, as soon as people were multiplied and the corrupt race of Cain increased, people “began,” after the birth of Enos, the son of Seth, “to call upon the Name of the Lord” Genesis 4:26, in public worship.
Abraham’s worship, in the presence of the idolatries of Canaan, is spoken of, under the same words, “he called upon the Name of the Lord” Genesis 12:8; Genesis 13:4; Genesis 21:33; Genesis 26:25.
Elijah says to the prophets of Baal, “call ye on the name of your gods, and I will call on the Name of the Lord” 1 Kings 18:24. Naaman the Pagan says of Elisha, “I thought that he would come out to me, and stand and call on the Name of the Lord his God” 2 Kings 5:11. Asaph and Jeremiah pray God; “Pour out Thy wrath upon the pagan that have not known Thee, and upon the kingdom (families Jerome) which have not called upon Thy Name” Psalm 79:6; Jeremiah 10:25; and Zephaniah foretells the conversion of the Pagan, “that they may all call upon the Name of the Lord, to serve Him with one consent” Zephaniah 3:9.
To “call” then “upon the Name of the Lord” implies right faith to call upon Him as He is; right trust in Him, leaning upon Him; right devotion, calling upon Him as He has appointed; right life, ourselves who call upon Him being, or becoming by His Grace, what lie wills.
They “call” not “upon the Lord,” but upon some idol of their own imagining, who call upon Him, as other than He has revealed Himself, or remaining themselves other than those whom He has declared that He will hear. For such deny the very primary attribute of God, His truth. “Their” God is not a God of truth.
But whosoever shall in true faith and hope and charity have in this life worshiped God, “shall be delivered,” i. e., out of the midst of all the horrors of that Day, and the horrible damnation of the ungodly. The “deliverance” is by way of “escape” (for such is the meaning of the word , “he shall be made to escape, slip through” (as it were) perils as imminent as they shall be terrible.
Our Lord speaks in a similar manner of the same Day, “Watch ye therefore and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man” Luke 21:36.
Those who so call upon Him in truth shall be heard in that day, as He says, “Ask and it shall be given you; Whatsoever ye shall ask the Father in My Name, He will give it you” Matthew 7:7; John 16:23.
We are created to worship Jesus in spirit and in truth, John 4:24
