Isaiah 55:12 “For you shall go out with joy, And be led out with peace; The mountains and the hills Shall break forth into singing before you, And all the trees of the field shall clap their hands.
Although the people of Israel had great joy out of being led out of Egypt in peace, these words are more focused on the joy and peace we have from living with God.
Not the joy and peace we will have when we get to heaven but the joy and peace we see, feel and touch when we are saved from sin, bonds, slavery, whatever.
There is no more joy than knowing you have eternity ahead of you!
