The way to receive God as our salvation is to draw water from the springs of salvation, i.e., to drink Him (Psa. 36:8; John 4:14; 7:37; 1 Cor. 12:13; Rev. 22:17). To be our salvation, the Triune God was processed to become the life-giving Spirit as the living water, the water of life (1 Cor. 15:45; John 7:37-39; Rev. 21:6; 22:1, 17). When the living water enters into us, it permeates our entire being, causing us to be nourished, transformed, conformed, and glorified (Rom. 12:2; 8:29-30). Both the Old Testament and the New Testament show that God’s practical salvation is the processed Triune God Himself as the living water.

Strength and song both indicate experience. When God’s salvation is experienced by us, it becomes our strength, and eventually it will be our song, our praising.

A shortened form of Jehovah.

This verse clearly reveals that salvation is God Himself. In the New Testament Jah Jehovah, who is salvation, is Jesus, the incarnated God (Matt. 1:21 and note Matt. 1:21^1b; Luke 2:30 and note Luke 2:30^1a).

Or, give thanks to.

A ringing shout is a shout that continues to sound. Joy is inward, but rejoicing (v. 3) involves some activity to express the joy that is within. This rejoicing is related to giving a ringing shout, that is, to rejoicing in a continuing way.

This is a matter of preaching the gospel, of telling others of the deeds of Christ and reminding them that His name has been exalted (Phil. 2:9), i.e., that He has ascended and is now in the heavens. Cf. 1 Pet. 2:9b.

By calling on the name of the Lord with rejoicing and praising, we draw water out of the springs of salvation. See Acts 2:21 and notes.

The fountain is the source, the spring is the gushing up, the issue, of the source, and the river is the flow. The term the springs of salvation implies that salvation is the source, i.e., the fountain. God as our salvation is the fountain (v. 2); Christ is the springs of salvation for our enjoyment and experience (John 4:14); and the Spirit is the flow of this salvation within us (John 7:38-39).

Christ as the life-giving Spirit (1 Cor. 15:45) is the many springs of salvation gushing up from the fountain of the Triune God’s salvation, from whom the believers may draw the water of life for their enjoyment (v. 3a; John 4:14; Rev. 21:6). As God incarnated, Christ is the very embodiment of the Triune God (John 1:14a; Col. 2:9). Jesus, Jehovah our Savior and our salvation (Matt. 1:21), has become the source of our eternal salvation through the process of His vicarious death for the accomplishing of God’s eternal redemption (Heb. 5:9; 9:12). Based on His redemption, He as our Redeemer becomes our Savior and our salvation.
