Peter preached the gospel of the grace of Christ. to Cornelius ..no repentence used
This is childish and insane.
The whole of scripture is about sin, the sin of man in their hearts, their lack of understanding and communion with the Lord, their desire to follow their lusts which lead to death.
The temple is about recognition of sin, and offering sacrifices to take away the punishment and effect of sins.
The gospel is preached "Repent and believe"
But now repentance is old covenant and new covenant because the writer did not say they repented, it means you just need to change you mind about God and believe.
This is so simple and so simply wrong.
Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit."
Acts 2:38
In the past God overlooked such ignorance, but now he commands all people everywhere to repent.
Acts 17:30
I have declared to both Jews and Greeks that they must turn to God in repentance and have faith in our Lord Jesus.
Acts 20:21
he Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.
2 Peter 3:9
Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
Rev 2:5
I have given her time to repent of her immorality, but she is unwilling.
Rev 2:21
The rest of mankind who were not killed by these plagues still did not repent of the work of their hands; they did not stop worshiping demons, and idols of gold, silver, bronze, stone and wood—idols that cannot see or hear or walk.
Rev 9:20
Repentance is preached before Jesus, by Jesus and after Jesus. If anyone cannot simply read this consistency then they no longer understand language meaning. But hey, if you cannot understand this and have a spirit of blindness, who am I to suggest the Lord has not given you over to spiritual blindness.
