Therefore let all the house of Israel know assuredly that God has made this Jesus, whom you crucified, both Lord and Christ (Acts 2:36, NKJV).
Why did the house of Israel crucify Jesus? The Messiah they longed for came to them, and Israel rejected Him (John 1:11). The fundamental reason the rulers and the mob crucified the Lord of glory was their unbelief (1 Cor. 2:7-9; Matt. 27:23-25). They did not believe Christ’s report (message) even after seeing His works (Isa. 53:1; John 12:37-40; 5:31-47). Neither did they believe the prophets who foretold of the Messiah (John 5:39-40; Luke 4:16-29). Notably, Peter said, “Yet now, brethren, I know that you did it in ignorance, as did also your rulers” (Acts 3:17). They were without knowledge (ignorant), not because the truth was unavailable to them, but because they chose to ignore it. The house of Israel ignored the truth of God and crucified the Savior in their unbelief. (1) They ignored the prophets (Acts 3:18). They ignored the words of Jesus (John 8:37-47). (3) They ignored the works of Jesus (John 10:31-39). Even many rulers who believed refused to confess Jesus to avoid being rejected by men (John 12:42-43). We point out Israel’s unbelief to warn the Israel of God (the church, Gal. 6:16; 1 Tim. 3:15; 1 Pet. 2:4-5). Christians can develop evil hearts of unbelief and fall from the living God (Heb. 3:12). When we sin willfully “after we have received the knowledge of the truth,” a “certain fearful expectation of judgment” and “fiery indignation” awaits (Heb. 10:26-27, 31). Ignorance is not a justifiable defense. Do not ignore the Messiah and His gospel. “Repent and be converted,” and live faithfully to Christ each day (Acts 3:19; 2:37-42).
