Hundreds of years ago, the Egyptian ruler Pharaoh asked the question, “Who is the Lord, that I should obey Him?” (Exodus 5:2). That question is still asked today. It is not an easy question to answer, because to do so we must use our finite minds to try to grasp the infinite. There are some things about God that we may never fully understand until we face Him in eternity (Job 11:7; Psalm 145:3; 1 Corinthians 13:12). But with the help of the Holy Spirit, there are many things we can grasp and should know about God.
Knowing what God is like is foundational to knowing God Himself, and knowing God is the essence of being a Christian.
