At one point along the Saguenay River in southeastern Canada, the water flows through a chasm between two rugged rock formations. Their pinnacles tower over 1,600 feet into the sky. Early pioneers were so awestruck by these majestic crags that they named them Trinity and Eternity.

The two great truths expressed by these words create a sense of awe in the heart of every Christian. The Bible tells us of God's eternity—His timeless existence (Psalm 93:2), and His triune nature—the threefold expression of Himself as God the Father, God the Son, and God the Holy Spirit (Matthew 28:19).

Both of these affirmations baffle our minds. If we try to comprehend either of them, the question asked by Job's friend comes to mind: "Can you search out the deep things of God?" (Job 11:7). The answer is obvious. When we try to behold the triune God, we feel like someone who gazes up into the midday sun to study it.

At the heart of the Christian faith is mystery, because at the heart of our faith is the eternal, triune God. We have the Father who loves us, the Savior who died for us, and the Spirit who helps us to be holy. This divine mystery gives us reason to bow down and worship our eternal God.    — Haddon W.
