Pastor Phil emphasizes the significance of waiting on the Lord during the Advent season, highlighting that it is a time of expectation for both the coming of Christ as a baby and his eventual return. He uses the story of Simeon, who patiently awaited the Messiah, to illustrate how we should embody righteousness, devotion, and openness to the Holy Spirit as we navigate our own waiting periods. By reflecting on Simeon's joy upon seeing Jesus and understanding that true salvation lies within him, Pastor Phil encourages the congregation to trust in God's promises and maintain hope, even amid life's uncertainties and suffering. The sermon culminates in a call to partake in communion, a practice that connects believers to Jesus' sacrifice while looking forward to his return.
