Why did God perform the signs in John's Gospel?
God performed the signs in John's Gospel to point the nation of Israel to their dire need. The eternal Creator God was performing them, yet His purpose was to show Israel their need before He could fulfill all the covenant promises.
Les explains that as we deal with the signs in John's Gospel, it is the eternal Creator God performing them. However, He is pointing them to the nation of Israel to show them their dire need before He could fulfill all those covenant promises. This fits the broader context where believing Jews in Acts were still law-keepers, not yet told to stop Temple worship or Law observance, indicating Israel's condition before the covenants were fulfilled.
