This sermon focuses on the Lord's Supper as a threshold moment, encouraging believers to look back at Christ's sacrifice, look around at present blessings and community, and look forward to future promises. Pastor emphasizes that Jesus, with eternal perspective, instituted communion knowing the full scope of God's plan from eternity past to future glory. The message calls believers to examine themselves, confess sins, and participate in communion with gratitude for redemption, present grace, and the hope of the Marriage Supper of the Lamb in heaven.
