Under the new covenant, to ‘call on the name of the Lord’ is directly connected to being baptized for the remission of sins2,3. It follows one’s hearing and belief in the gospel (of truth)1,2,3 and includes the ongoing worship8 and service to each other9,10,11. God hears all who call on His name in this way5 (it is not an “inward call”). He responds by setting them apart with His Spirit4,9 as He promised3.
The concept of ‘calling on the name of the Lord” is seen throughout all periods of Scripture – since shortly after creation6-to Abram7,– through the Mosaic law5,12,13 and into the first century Christian age1,2,3,4,8,10,11. David describes5 the mechanism (God’s word) and the result (God’s salvation). The same mechanism and result carry through to the first-century Christian’s “calling” as well1,4,8,10,11.
With all of these references to “call on the Lord”1,2,3,4,5,6,7,8,9,10,11,12,13 – Old and New Testament – we never read about it being some sort of “sinner’s prayer” or a “call to Jesus” to come into one’s heart or life. Instead, what we read about are praying people (“God-seekers” if you will12) that are confronted with the gospel message and consistently respond in obedient faith.
