Know that you Know!
Our faith in the character of God is the doorway that opens up our lives toward God.
The eternal life we have from God comes through our faith in His Son. This positive affirmation is followed in the tradition of Old Testament parallelism with the statement stated negatively. There is no eternal life apart from the Son of God. Jesus Christ is not one of several possible saviors, or a shepherd among the shepherds; Jesus Christ is the Savior, the true shepherd. God has spoken in His Son, and we must listen to that speech. Karl Barth says:
When we pronounce the name of Jesus Christ, we are not speaking of an idea. The name Jesus Christ is not the transparent shell, through which we glimpse something higher—no room for platonism here! What is involved is this actual name and this title; this person is involved … so we confront God. God really encompasses us in Jesus Christ “on every side.” Here there is no escape. But there is also no drop into nothingness. In pronouncing the name of Jesus Christ we are on the way. “I am the way, the truth, and the life.” That is the way through time, the center of which He is … .1
John does not make the Christian church the center nor is the life a reward for the mastery of secrets. Eternal life is in Jesus Christ. That is the Good News—not a burden but an adventure.
Our lives work better when we live from the true center, Jesus Christ.
