How do we bless the Lord with all our hearts?

To bless the Lord with all our hearts means that our worship is from a place of deep affection, sincerity, and devotion. It involves our mind, will, and emotions, acknowledging His unsearchable riches in Christ. The Psalmist urges us to bless the Lord 'oh my soul,' emphasizing an inward, sincere expression of gratefulness. This aligns with the Reformed perspective that true worship is a heart work prompted by the Holy Spirit, who renews our hearts and minds, enabling us to express true reverence and love towards God for His salvation and ongoing grace.
