The simple answer that every child learns in church, in Sunday School, and in other children’s programs is that our only Mediator is the Lord Jesus Christ who was sent to us to redeem us from our sins by substituting himself in our place, paying the penalty for our sins and imputing to us his righteousness. And as adults we say, “Amen and Amen.” And all believers respond, whether child or adult, “Praise God! Hallelujah!”
There are many other religions floating around this old world, but every other religion that I am aware of, leaves you in the despondency of human works or fate. They may call it various things — merit, karma, kismet, etc…but it all boils down to one thing: despair. I can’t do enough good works to satisfy my own soul, let alone the demands of a perfect God. And then the idea of fate — I am bound to my miserable lot, so why bother growing and seeking maturity in faith or doing good works. In the end — grief and despair overwhelm. What a radical difference there is between Biblical Christianity and any other faith that the world has to offer!
The real question, for you who confess Christ is whether you really live like you believe Christ is your mediator and intercessor before God. Do you strive to live in a way that honors him? Do you seek to live obediently to his commands? If not, can it be said that you really believe all this you say about the person of Christ? In principle, the things we believe are seen in the way we live. Is Christ visible in the way you live your life? Is he visible in the way you worship? Is he glorified in you?
