Jesus is the same, yesterday, today, and forever.  He does not change. God the Father does not change.  Why is that important?  Because our world is in continual change - most of which is not for the better.  We need to have stability in our lives and there is only one way for us to have it and that is with God, our Father and Jesus, our Savior.  We must not allow ourselves to be moved by the things in this world that would steal our peace and cause us anxiety.  What we see with our natural eyes will change but the things we see with our eyes of faith - the eternal things of God never change.  They always stay the same.
