Remember how God has led us in the past. It's in the Bible, Deuteronomy 8:2, NIV. "Remember how the Lord your God led you all the way in the desert these forty years, to humble you and to test you in order to know what was in your heart, whether or not you would keep His commands."
Remember to make God a priority while you are young. It's in the Bible, Ecclesiastes 12:1, NIV. "Remember your Creator in the days of your youth, before the days of trouble come and the years approach when you will say, 'I find no pleasure in them.'"
Remember God's holy day. It's in the Bible, Exodus 20:8-10, NIV. "Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God."
