1 John 5:20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
The Son of God has entered our world as one of us humans, and when He finished His mission, He gave us an understanding. This is the Lord’s promise: we understand. We understand Life. We understand Truth. We understand what it’s all about. He promised us faith to see. This clarity of vision comes from knowing Jesus. Knowing is believing and having a relationship with Him; we are in Him.
When we believe in the Son we have Him; when we have Him we have Truth, Life, and Love. We have all of God. We know all that we need to know; we know what what God has revealed.
We do not understand all mysteries, but we personally know Him who does. We are in Christ, who is Truth and Life, who has promised us all the riches of God and His Kingdom. We need nothing more, but we spend the rest of our days seeking to understand Him better, to know Him more closely, to open up more of the gifts, to walk in His love, to enjoy Him, and to realize what we have been given. Then in eternity we shall know as we are known.
