Act 28:30 And Paul dwelt two whole years in his own hired house, and received all that came in unto him,
Act 28:31 Preaching the kingdom of God, and teaching those things which concern the Lord Jesus Christ, with all confidence, no man forbidding him.
Act 28:23 And when they had appointed him a day, there came many to him into his lodging; to whom he expounded and testified the kingdom of God, persuading them concerning Jesus, both out of the law of Moses, and out of the prophets, from morning till evening.
I can quote scrioptures too.
Acts 21:18-21
18 On the following day Paul went in with us to James, and all the elders were present.
19 When he had greeted them, he told in detail those things which God had done among the Gentiles through his ministry.
20 And when they heard it, they glorified the Lord. And they said to him, "You see, brother, how many myriads of Jews there are who have believed, and they are all zealous for the law;
21 but they have been informed about you that you teach all the Jews who are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children nor to walk according to the customs.
NKJV
Galatians 2:16
16 knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified.
NKJV
