We say, in order to become rich we must gain as much as we can. God says, in order to be rich we must give everything away.
We say, in order to become famous we need to let everyone else know of our great deeds. God says, if we really want to become famous we must become lowly, and He will see that we are lifted up.
It seems that each of our human perceptions is the exact opposite of the Truth. Perhaps that's because we are only looking in a poor mirror. Ever try to trim your hair while looking in the mirror? It's nearly impossible because your hand wants to go in the exact opposite way it needs to go. So it is with God. We may see what we are supposed to do, but we see the mirror image of it, and go the opposite way. Just as we have to have someone else trim our hair we need someone else to direct our life's actions.
In Some Have Entertained Angels, by James Robert Wilson, as well as in our Christian walk, the only way to be victorious on the spiritual battlefield is to surrender. That may sound absurd, but I'm not talking about surrendering to the enemy. I'm talking about surrendering to God. There is so much in us that opposes God, even after we become Christians, that in order to truly become useful to Him as His soldiers we must surrender ourselves to Him. If you fail in this please don't become discouraged. Surrendering ourselves to God is a lifelong process. The more we surrender the more we become like Christ. Here is one very good place to start; "And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God." (Romans 12:2) This means that we are to follow Paul's instructions found in Ephesians 5:26, "That he might sanctify and cleanse it with the washing of water by the word."
As you can see, and read some really graphic examples in Some Have entertained Angels, we need to humble ourselves before God in order to be of any use to Him. The more we are humble before Him, the more useful we are to Him, and the more we find ourselves living in victory instead of defeat. Defeat is not characterized so much by our stumbling and falling as it is by our giving up. This we must never do. To get a real grip on this you'll have to do your own study of enduring until the end, although we see even that in this little book.
