What does the Bible say about comfort for a troubled soul?

In Colossians 2, Paul expresses a desire for the hearts of believers to be comforted through a deep understanding of God's truth. The comforters are not simply the words spoken, but the power of the Holy Spirit that brings these truths alive in our hearts. The mystery of God, which encompasses the roles of the Father, Son, and Holy Spirit, offers believers a foundation of wisdom and knowledge that leads to assurance and peace, even in troubling times. This assurance is rooted in faith and understanding who God is and how He works in our lives.
