Why is it important to understand God's purpose in deliverance?

God's purpose to deliver the Israelites from Egypt, as revealed in Exodus 7, emphasizes His commitment to fulfill His promises. The specific mention that He will harden Pharaoh's heart ensures that the deliverance is entirely attributed to God's power and purpose. This narrative aligns with the broader biblical theme that demonstrates God's ongoing relationship with His people. Recognizing that God's purposes are singular and unchanging, as indicated in Isaiah 14:27, provides believers with assurance and hope. It reassures us that no matter the circumstances, God's plan is providentially directed towards the good of His people and His glory. Understanding this encourages Christians to trust in God's timing and methods in their lives.
