1 Samuel 11:14-15 Then David Samuel to the people, Comem and let us go to Gilgal, and renew the kingdom there. And all the people went to Gilgal, and there they made Saul king before the Lord in Gilgal; and there they sacrificed sacrifices of peace offerings before the Lord; and there Saul and all the men of Israel rejoiced greatly.
Saul had just led Israel in a resounding victory over the Ammonites. To thank God and give Him the glory, Samuel gathered the people to renew the kingdom. The Lord had already given the kingdom, but sinners need to periodically renew, refresh, personalize, make present, and activate the power and the blessings of the kingdom of God in their hearts and lives. This we do weekly in public worship with Communion and daily in morning devotions remembering our Baptism. The kingdom is always in us, but we are not always aware of it.
The sacrifices of peace offerings are expressions of worship and thankfulness for the Gospel. The sacrifice that avails before God is the death of Christ on the cross. This sacrifice is announced every Sunday. We make peace with God by believing in Jesus and by receiving the gospel that proclaims the victory of Christ.
In our daily and weekly worship we rejoice greatly because we are reminded of the rich blessings of the kingdom of God within and of the awesome love of God for sinners like me. With these constant reminders we are renewed in spirit and filled with joy. With enough reminders we are continually in a state of renewal, thankfulness, and great joy.
