The Spiritual realm is much different than the realm of the world. It sees things differently, judges things differently, and estimates things much differently than the world. What may seem little through the world’s eyes can be huge in light of spiritual matters. Listen to “Pointing to Christ” as Dr. Martyn Lloyd-Jones preaches from John 1:41–42 and expresses this truth through the lives of Andrew and Simon Peter. He uses these men of the New Testament to show that those whom the world may look at as simple fishermen, God can use as kingdom bearers and messengers of the gospel. He then encourages that it is the same today. Christians may look at themselves and wonder how they could serve the Lord, but God tells them to simply come to Him, and through His own strength and power they too can play a part in the kingdom of God. It is essential to realize that they cannot do it on their own, but must rely upon Him and His own strength. Lastly, they can also be encouraged by seeing how this truth points to the fact that God cares about each one personally and wants them to be a part of His great plan.
