Pastor Matt begins this first sermon in a series on anxiety by sharing his own struggles with fear and worry, emphasizing that anxiety is fundamentally a spiritual problem. Using Philippians 4:4-5 as his foundation, he explains that the surprising command to "Rejoice in the Lord always" is our starting point for battling anxiety, with the encouragement that "the Lord is at hand." The simple solution to anxiety is fully surrendering to Jesus Christ, who brings peace with God, peace within, and peace with others.
