"Behold, God is my salvation; I will trust, and not be afraid: for the LORD JEHOVAH is my strength and my song; he also is become my salvation. Isaiah 12:2"
"Behold" means see with the eyes of your spirit, grasp and have fellowship with it. In other words, the Prophet Isaiah is telling us that if we can only see with the eyes of our spirit, grasp and have fellowship with the Lord, we will come to the conclusion that God is indeed our salvation; we will trust in Him and not be afraid.
Furthermore, we will know Him by the name of Jehovah, our strength and our song. The opening scripture should encourage people to be intimate with the Lord and Savior Jesus Christ now and forever.
"The LORD is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower. Psalms 18:2"
The opening scripture speaks so much about who God is to the Psalmist. The Psalmist was talking from a personal relationship or personal encounter with the LORD.
He said the LORD is his rock, fortress, deliverer, God, strength, trust, buckler, horn of salvation, and high tower. Nine personal encounters produced nine attributes of God.
In the New Testament, Jesus Christ asked His disciples, "Who do you say that I am?" Peter answered, "You are the Christ, the Son of the living God", Matthew 16:15-16. Dearly beloved, have you had any personal encounter with the LORD?
