Strength And Song And Salvation

Psalm 118: 6, 14

The Lord is for me; I will not fear; what can Man do to me? 

If you know that the Lord God Almighty is on your side (because you're on His side), then you don't need to be afraid of anything anyone else can do to you. 

The Lord is my strength 

Wherever we find ourselves unable to do something we need to do, He is strong enough to do it through you. 

and my song, 

He is the One Who is to be praised with music, His fame spreads throughout the whole of Creation through the songs of Men and Angels. 

and He has become my Salvation.

And He has come as our Redeemer, and acquired the Name of Jesus, to 
be sin for us, Who knew no sin; 
Jesus is the Son that was given to us when the new Child was born (Isaiah 9:6), and God the Son, the Lord, has become our Salvation as the Lamb of God. He bore our very sin-nature, encompassing all the sins that result from it, for each of us individually, as God saves people one-by-one.
that we might be made the rightousness of God in Him (II Corinthians 5:21). 
His Blood washes us as white as snow, pristine, without a spot or wrinkle, perfectly pure. To fit us to live with Him where He lives.

So He has become our Salvation, our rescue from the power of sin right now in this World. 

O my Father, You are my strength, I am powerless and weak. Because I trust You, because You have chosen me, I will not fear whatever happens to me in this World.

You are for me, so You will continue to hold me in Your hand, protecting me from Your wrath that shall come upon the whole World in the Day of Wrath.

You are my song that I will sing until the whole World hears! Or until You deem my purpose here finished. 

And You will receive all the honor, all the glory, all the praise, forever!

Even so, come, Lord Jesus!
