Summary: In chapter 4 of Revelation, we enter into the presence of God, standing at the Throne of God. We see the greatness of four living creatures that begin a song of praise that everyone partakes of, “Thou Art Worthy, O Lord.”
1. He is Worthy, Because of Who He is
a) He is The Son
b) He is The Savior
c) He is The Supplier
2. He is Worthy, Because of What He did
a) He was Devoted, in His Walk
1 Peter 2:21-22 (quickview)  says; For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps: Who did no sin, neither was guile found in his mouth:
b) He was a Deliverer, to the Weary
c) He Died, for the Wayward
Mark 2:16 -17 (quickview)  says; And when the scribes and Pharisees saw him eat with publicans and sinners, they said unto his disciples, How is it that he eateth and drinketh with publicans and sinners? When Jesus heard it, he saith unto them, They that are whole
have no need of the physician, but they that are sick: I came not to call the righteous, but sinners to repentance.
1 Peter 1:3-5 (quickview)  says; Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead, To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you, Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
3. He is Worthy, Because of Where He is
He is Seated
purged our sins, sat down on the right hand of the Majesty on high:
What about me? Am I worthy?
Satan continually tells you that you are not worthy. However, John 10:1-10 (quickview)  tells us; The thief (Satan) cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
"You Are Worthy"
Every Christian should realize that they are Worthy because of the facts found in God's Word.
I am Worthy to Pray, because I've been cleansed by the blood of our Lord and Savior Jesus Christ.
a) When we mess up he is there waiting for us to call upon him.
