Believe it or not, the title’s question above has an incredibly simple answer, but the things you must understand to grasp it are not so easy. Let us start with another question.
“In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made. In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it.” John 1:1-5.
“Jesus said to them, ‘Have you understood all these things?’ They said to Him, ‘Yes, Lord.’ Then He said to them, ‘Therefore every scribe instructed concerning the kingdom of heaven is like a householder who brings out of his treasure things new and old.’” Matthew 13:51-52.
“I waited patiently for the Lord; and He inclined to me, and heard my cry. He also brought me up out of a horrible pit, out of the miry clay, and set my feet upon a rock, and established my steps.” Psalm 40:1-2.
“And he showed me a pure river of water of life, clear as crystal, proceeding from the throne of God and of the Lamb. In the middle of its street, and on either side of the river, was the tree of life, which bore twelve fruits, each tree yielding its fruit every month. And the leaves of the tree were for the healing of the nations. And there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him.” Revelation 22:1-3.
