Foundations: God Three in One

The one true God of the Bible, from beginning to end, has been chasing down His creation to reconcile a broken relationship with a sinful people. And, ever since the beginning, He has had a plan of redemption for us. As we see this plan unfold, we see three distinct persons of God, The Father, The Son, and The Holy Spirit. All three wholly and fully God, yet all three described individually and in depth in His Word. How can we reconcile this reality and who are the three persons of God?
