Searching for Him isn't like looking for a needle in a theological haystack. He isn't hiding. He isn't unknowable. He isn't some mysterious force or philosophical construct that you can't quite grasp or attain.
In fact, the opposite is true. His Son appeared to all in bodily form. Jesus, "the radiance of God's glory and the exact representation of his being," walked this earth in plain sight so that anyone seeking God could find their way to Him.
God's not hiding. He's been looking for you for a long, long time.
Do you know why? Because He wants you to know who He is...and who you are, too. He wants you to know that you're the object of His affection, created in His image, made by and for Him.
He wants you to know that the Unknown God has a name. He wants you to know that the incredible desire for worship rooted deep inside your heart was crafted for Him.
