The Israelites of the Exodus did not enter into the promised land of rest because they doubted God’s promise. Today, if you do not believe in Christ, you will not enter His rest. Today, if you hear God’s voice, you must believe and accept Christ as your Lord and Saviour. There is a heart shaped vacuum in your heart that only God can fill. You will be restless until this heart shaped vacuum in your heart is filled by the Holy Spirit. St. Augustine said, “You have made us for yourself, O Lord, and our heart is restless until it rests in you.”
