The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness! MAT 6:22-24.

This principle marks one passion which presses all others into subjection. Every evil passion of our heart must be pressed into subjection to the passion to walk in the footsteps of Christ. Every desire of our heart that comes against this principle must be brought into subjection.

This brings spiritual warfare within our heart. We desire to walk in the footsteps of Christ, but the old man of sin sticks up his ugly head tempting us to walk after the things that please the flesh.

Scriptures often use setting out to sea as an illustration of our spiritual life. As a navigator setting out to sea, we must set our compass on our eternal destination which is Christ.

A navigator cannot allow the luxury of one place, or the gain of another, to detain him. His compass is set for one certain harbor, and he doesn't let his ship stray from the set course. If he does, he will miss his port.

We too are often lured way by so many thing of this world. The flesh lures us here and there, but if our eye is single, it will be looking on Christ. He will become the entire object of our desire wherein we will walk and follow in His footsteps. This is what is meant by singleness of eye.

The singleness of eye does not mean a person sees only one thing. He sees the heaven above and the depths over which he rides, but his eye, as the navigator's compass, is set on the object of his faith.

When we single out Christ as the object of our salvation, our faith, and the center of everything, we see that heaven is the reward. We see the depths of corruption from which Christ saves us, but our eye is fixed on the blessed Redeemer; we are God-seekers.

We may well see the heavens above and depths over which we ride, but our eye, as the navigator's compass by which he steers his course, is on the desired haven. The Word of God is the compass which keeps us on course to our desired haven—to be with Christ.
