Tammy designed this window with the Salvation message in mind.  To understand its meaning, start from the bottom window and work upward. 

Jesus is the Alpha and Omega, the beginning and end.  The Word of God points to the Lamb, the Messiah, who became the ultimate sacrifice for our sins.  Having conquered sin and death on the cross, our risen Savior is the Victorious King who will one day return for us.  Jesus said that He is the Vine and we are the branches.  We need to stay in Him in order to bear good fruit.
