He is Lord of all

Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:  but in every nation he that feareth him, and worketh righteousness, is accepted with him.  The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all:)  that word, I say, ye know, which was published throughout all Judæa, and began from Galilee, after the baptism which John preached;  how God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him.  And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree:  him God raised up the third day, and shewed him openly;  not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead.  And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead.  To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.  While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. – Acts 10.34-44

After laying the groundwork that the message he is preaching is for everyone he moves to the next major point – that Jesus is Lord of all. ‘The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all)’

The idea that the Lord God is one Lord goes way back to the Law. It was the foundation of the Law and Jewish belief. That fact was clearly preached that since Jesus was God in flesh that He is Lord of all. Preaching this to Gentiles had a different impact than to the Jews. The Gentiles under the influence of Greece had a whole pantheon of gods. We know they today in the days of our some months and some days. People had to be aware of all these gods and how to appease them.
But now Peter preached to them that all their gods were of no use. Jesus was Lord of all and any hope for eternity rested in Him. At the end of the message Peter will say that Jesus is not limited to anyone but is there for anyone who believes.

We too must remember today that Jesus is Lord of all. All creation is under His control. He is the immortal, all knowing, all powerful, ever present, and unchanging Lord of all creation. There can only be one true Lord of all and Jesus is that one true Lord.

He is worthy of our worship. He is worthy of our following. He, as Lord of all is worthy of our all.
