Biblical Study While Living with Coronavirus, lesson 3. Mark taught from Isaiah 40: Comfort for God’s people. In this text, we read and understand God’s broken heart for His people. Israel had lived unfaithful to God, and He would tear Israel apart. Jerusalem walked away from God, but Jesus is the return of God to His people. Matthew 28:20 tells us that Jesus is with us always to the end of the age. In applying the text to today: In Isaiah 40:29-31, God promises power to the faint, strength, and His presence. Mark concludes with a list of some of God's promises taken from the Bible. Comfort ye my people. God is in control.
