Jesus placed such a strong emphasis on faithfulness to God. He did this because faithfulness is an expression of trust. It's an expression of realizing God really does deserve our faithfulness, our trust, our obedience, our devotion, above all else. When you disobey doctor's orders, you're not just saying something about the orders, you're saying something about the doctor. And when you disobey God, you're not just saying something about his commands that you're disregarding, you're saying something about the God who gave those commands. And so, faithfulness is an expression of trust. It's an expression of seeing God for who he is, and then, of course, doing what he says. And so, when Jesus comes, he submits to the will of the Father as the Son, but he also displays for us what our lives as human beings should look like, obeying God, being faithful to him. Jesus becomes the faithful one, the one who we put our faith in because he always expressed faithfulness to God by obeying God. So, faithfulness to God is an expression of obedience, it's an expression of daily devotion and trust in who he is. Paul, in Romans, talks about the Christian life in his apostolic ministry as one that should lead to the obedience of faith. It's a beautiful expression which in some ways summarizes the Christian life. We see God for who he is, we put our faith in him, and that naturally leads to obedience. We obey the God that we trust.
