In today's verses, John wants us to know that "Jesus is the Christ, the Son of God" (John 20:31). But why is it so important that we believe He is God's Son?
The most obvious reason is because our salvation, and therefore our eternal destiny, depends upon our faith in this truth. But after salvation, Christ's divine identity should continue to affect us.
For one thing, knowing the Son leads to a deeper understanding of the Father. Since Jesus is both God and man, He is uniquely qualified to provide us with such insight. As we study His life, the aspects of God's character and ways that are difficult for our human minds to grasp come to life through Christ's teaching and example.
He also shows us who we can become. The Lord is committed to transforming each of His followers into the likeness of His Son. Though we won't reach perfection in this life or ever attain Christ's divine attributes, His character can be worked out in us as we yield to the Holy Spirit. Jesus is our example for godly attitudes, words, and actions.
Another way Christ affects us is by inspiring our gratitude. He left the glories of heaven in order to become our Savior, and when we recognize that sacrifice, we are filled with thankfulness and praise.
Let Jesus motivate you to live in purity. He abides within every believer through His indwelling Holy Spirit. That means selfish and sinful thoughts, attitudes, words, and actions have no place in our lives. Be mindful that He is always with you, and let Him direct your choices and purify your life.
