And being let go, they went to their own company, and reported all that the chief priests and elders had said unto them. And when they heard that, they lifted up their voice to God with one accord, and said, Lord, thou art God, which hast made heaven, and earth, and the sea, and all that in them is: Who by the mouth of thy servant David hast said, Why did the heathen rage, and the people imagine vain things? The kings of the earth stood up, and the rulers were gathered together against the Lord, and against his Christ. Acts 4:23-26
Again the Apostle Peter quotes the Old Testament (Psalm 2) to show how Jesus is the fulfillment of Christ. As prophesied by David and all the prophets of the Old Testament, Jesus fulfilled all things. When the religious leaders were challenged by the Apostles, they had no response because you can’t deny the Word of God and everything that was fulfilled by Jesus
The religious leaders were trying to make examples of the Apostles by challenging them but what they actually did was strengthen the faith of the Christian believers. If the religious leaders couldn’t even disprove that Jesus is The Christ, then who would? Nobody because Jesus fulfilled the entire Old Testament!
For of a truth against thy holy child Jesus, whom thou hast anointed, both Herod, and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together,For to do whatsoever thy hand and thy counsel determined before to be done. And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word, By stretching forth thine hand to heal; and that signs and wonders may be done by the name of thy holy child Jesus. Acts 4:27-30
What made the Apostles preach with such boldness? Why were they willing to give up everything for the movement and even willing to lose their life for Christ? Because they knew Jesus is The Lord and it was reinforced by the signs and wonders performed by Christ and the Apostles through the Holy Spirit!
And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness. And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common. Acts 4:31-32
Notice after the Church prayed together in unity, they were filled with the Holy Spirit. They preached the gospel with boldness and they took care of each other as a family, as the body of Christ was meant to
May your faith be strengthened by the words of our Lord Jesus Christ, and the signs and wonders God performed through him and the Holy Spirit. May the Church be united and strengthened in Jesus Name Amen!
