The HELMET of SALVATION –
EPHESIANS 6:17
And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
MATTHEW 1:21
And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
2 TIMOTHY 2:10
Therefore I endure all things for the elect's sakes that they may also obtain the salvation which is in Christ Jesus with eternal glory.
The very name of Jesus in Hebrew is Y’shua (or as we would say, Joshua) which itself is a contraction of the Hebrew Ye’hovah Shuah or “Our God is salvation”. Note that Jesus doesn’t merely bring salvation; He is Himself our salvation (PSALM 35:3)! Thus we acquire this helmet of Salvation in the reception of the Son of God into our lives (JOHN 1:12), and “put[ting] on Christ (ROM 13:14; GAL 3:27)”. This salvation isn’t derivative (something we get from Him) of Jesus Christ so much as it's integral (to be complete and entire) in His Person.
