Why is being filled with the Spirit important for Christians?

Ephesians 5:18 instructs believers to 'be not drunk with wine, wherein is excess, but be filled with the Spirit.' This command highlights the importance of spiritual fullness over worldly indulgence. The filling of the Spirit empowers Christians to live in wisdom, fostering a lifestyle characterized by love, joy, and thankfulness. Moreover, it enables believers to edify one another through song and worship, cultivating a vibrant community of faith. Living under the influence of the Spirit aligns us with God's purposes and equips us to resist the temptations of a sinful world.
