Call

(1.) To cry for help, hence to pray (Gen. 4:26). Thus men are
said to "call upon the name of the Lord" (Acts 2:21; 7:59; 9:14;
Rom. 10:12; 1 Cor. 1:2).

(2.) God calls with respect to men when he designates them to
some special office (Ex. 31:2; Isa. 22:20; Acts 13:2), and when
he invites them to accept his offered grace (Matt. 9:13; 11:28;
22:4).

In the message of the gospel his call is addressed to all men,
to Jews and Gentiles alike (Matt. 28:19; Mark 16:15; Rom. 9:24,
25). But this universal call is not inseparably connected with
salvation, although it leaves all to whom it comes inexcusable
if they reject it (John 3:14-19; Matt. 22:14).

An effectual call is something more than the outward message
of the Word of God to men. It is internal, and is the result of
the enlightening and sanctifying influence of the Holy Spirit
(John 16:14; Acts 26: 18; John 6:44), effectually drawing men to
Christ, and disposing and enabling them to receive the truth
(John 6:45; Acts 16:14; Eph. 1:17).
