How do we know God's hand is strong in our salvation?

The strength of the Lord's hand in salvation is seen vividly in Exodus 13, where Moses tells the people to remember their deliverance from bondage. This deliverance was not achieved by their own efforts but solely by God's mighty hand. The repeated emphasis on this 'strong hand' throughout the passage signifies that salvation is determined by God's power rather than human ability. Similarly, in the New Testament, we see God's power displayed in the resurrection of Christ, affirming that only through divine strength can sinners be redeemed. This assurance is further echoed in Romans 15:4, which states that the Old Testament accounts were written to teach us about the hope we have in God’s promises.
