Those who believe in Christ are sealed and indwelt by the Holy Spirit at the time of salvation, but we are also commanded to be filled with the Spirit. Alistair Begg points out that this biblical directive is practical in nature, not merely emotional or esoteric. How are we filled? When our hearts, minds, and wills are ordered and transformed by the Word of God. Spirit-filled lives lead to Spirit-filled praise, enabling believers to sing and make melody in our hearts to the Lord who saved us.
