In 'A Call to Worship Part 1', Pastor Chuck Smith emphasizes the significance of worship through singing, drawing from Psalm 95, which invites believers to joyfully come before the Lord. He highlights that worship is a response to God's greatness rather than a means to receive blessings, encouraging congregants to express their gratitude and praise. Smith illustrates the importance of being sensitive to God's voice and warns against hardening our hearts, using the Israelites' experiences as a cautionary tale. He reminds us that God is present in both our valleys and mountaintops, and calls for a heartfelt, spontaneous worship that reflects our relationship with Him.

In this sermon, the preacher reflects on what will happen when the world comes to an end and everyone faces judgment. He emphasizes the importance of being right with God and accepting Jesus as Savior to be prepared for this day. The preacher highlights the signs indicating that Christ's return is imminent and urges believers to eagerly anticipate it. He concludes by quoting biblical passages that speak of God's victory over nations and the assurance of eternal life for the righteous.

F.B. Meyer emphasizes the necessity of cleansing the heart to restore the song of the Lord, illustrating that neglecting self-sacrifice and devotion leads to spiritual backsliding. He urges believers to examine themselves, confess their sins, and remove all uncleanness from their lives to prepare for a renewed relationship with God. Only through complete surrender and consecration can one experience the joy and music of a life in harmony with God's will. Meyer highlights that true worship and song arise from a heart fully devoted to God, and that neglect leads to a silence in spiritual life. The sermon calls for a return to a state of purity and dedication to reignite the joy of worship.
