When we look at Israel’s exodus from Egypt, God delivered them from the house of bondage and from the power of Pharaoh, but they were not delivered from sin itself. Ezekiel 20:5-10 indicates that the Israelites in Egypt refused to get rid of their idols. Joshua 24:14 and Amos 5 confirm that the Israelites carried their idols all throughout the wilderness journey and into the Promised Land. So, the Israelites were not delivered from sin, but from the power of Pharaoh, from slavery, and the environment where they learned idolatry.
During the Passover in Egypt, Israel was still sinning with her idols. God almost destroyed them in Egypt, but He restrained Himself for His own name’s sake. That Passover was about God’s overlooking Israel’s sins, not providing a payment. The Hebrew word for Passover means, “an exemption.” It was simply grace, a gift, rather than satisfying the legal demand of the law. The dominant theme of the Passover is the relationship, graciously initiated by God, and the peace and fellowship that results from God’s unmerited acceptance as part of His redemption process.
