"He established a decree in Jacob, and appointed a law in Israel, which he commanded our ancestors to teach to their children; that the next generation might know them, the children yet unborn, and rise up and tell them to their children, so that they should set their hope in God, and not forget the works of God, but keep his commandments." (Ps. 78:5-7)
Psalm 78 is not historical in the way we define history in the contemporary sense. Psalm 78 retells history for the purpose of teaching which leads to hope and obedience in the hearers. The psalmist wasn't just writing for the faithful of that time, but for future generations as well.
The teaching in Psalm 78 has the goal of guiding the faithful to offering their whole lives to God. Learning the decrees, laws, and stories of our spiritual ancestors, through Scripture, opens us to the spiritual power of the divine. We have an obligation to bring God's blessings to others, so they too can experience the joyous steadfast love of God.
Today, prayerfully reflect on those individuals who were your formal and informal teachers. How did they positively influence your development as a person and a Christian? Are there ways in which you are, or can be, a teacher of the faith? Perhaps you are feeling called to teach Church School on Wednesday or Sunday. Perhaps you are a parent, and are searching for new and ever more meaningful ways of guiding your child(ren) in the faith. Offer God your prayers for wisdom and commitment. Then, be open to God leading you in opportunities to offer your wisdom to others.
