Leviticus 26:13

I am the Lord, your God, which brought you forth out of the land of Egypt that ye should not be their bondmen, held in shameful slavery by a heathen nation; and I have broken the bands of your yoke, and made you go upright. The deliverance from Egypt was a proof and pledge of the fulfillment of God's promises, and the fellowship which the children of Israel enjoyed in Him was symbolic of the perfect communion which the children of God have entered upon with Him through the redemption of Christ. If we Christians believe and trust in God with all our heart, and walk in the ways of His commandments, then He will remain with us with His Word and Sacraments. Therefore we should also love and trust in Him and gladly perform the demands of His holy will.
