How do we know that prioritizing God is essential for Christians?

In Matthew 6:31-33, Jesus advises His followers not to worry about worldly things such as food and clothing, instead instructing them to 'seek ye first the kingdom of God and his righteousness.' This indicates that a church and its individual members must focus on God’s Kingdom, assuring them that their material needs will be cared for. Both the example of Mary, who chose the better part, and the teachings of Jesus highlight the critical importance of putting God at the center of our lives for true fulfillment and peace.
