Acts 10:1 There was a certain man in Cesarea called Cornelius.....
Cornelius was a devout man, a Roman centurion of the Italian Band, one that feared God with all his house, which gave much alms to the people and prayed to God always. God sent an angel to him who told him that his prayers and alms were come up for a memorial before God.
And he told him to send for the Apostle Peter to come and speak words to him by which he and all his household would be saved. God had regard for him because he feared Him and did righteous works, praying always and giving to His people the Jews. He loved Israel and blessed them, and, as God said to Abraham many years before, He that blesses you I will bless.
Peter came to his house and all his family and friends were gathered together to hear what he had to say to them. As Peter began to speak he said, Act 10:34 & 35,..... 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. Even though Cornelious was a gentile, he had fulfilled the conditions that God had set forth to be accepted
with Him; fearing God and working righteousness, so the Lord sent Peter to him to preach the Gospel to him and his family that they might be saved.
It is not enough to say only that God is no respecter of persons, which is absolutely true and proven through out the scriptures, or just to say,I believe in Jesus.
Act 10:42 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.
Jesus is the judge of all mankind and He has promised many times in scripture that at the judgement , when He returns, He is going to give unto every one of us according to our works. In vs 43 Peter said also that to Him give all the prophets witness that through His name, whosoever believes in Him shall receive remission of sins. Act 10:44 - 47: While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. For they heard them speak with tongues, and magnify God. Then answered Peter, Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?
It's not enough just to say you believe in Jesus. You must repent of all your sins and fear Him and work
righteousness. If we have evil works we must repent to Him, confessing our sins and turn from them and be cleansed by His shed blood, and be delivered to work righteousness, be washed by His Word, be filled with His Spirit, be led by His Spirit to fulfill all righteousness, and follow Jesus doing the will of the Father. Jesus said in Matt 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
