When considerable time had passed and the voyage was now dangerous, since even the fast was already over, Paul began to admonish them to not continue, because he perceived that not only would there be a loss of the cargo but also of their lives.

 Good morning. This comes from the first chapter of first John. God is light, and in Him there is no darkness at all. If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth; but if we walk in the light as He Himself is in the light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. In math, which is my native tongue, when we say that A equals B, it means they are exactly the same. But in Greek that's not true. When it says that God is light, it does not mean that light is God. God is love does not mean that love is God. In Him there is no darkness. So if there is darkness, it means that we have stepped away from Him – out of the light. Sometimes little children are afraid of the dark. Most of the time they get used to it little by little. We say that they grow out of it. The same can be said about the darkness of being away from Him. When we become Christians, we are afraid of the dark – being away from Him. But sometimes we get used to the dark little by little. We are no longer afraid of being in the darkness. We no longer practice the truth. I don't know if it's still the way they train bank tellers. They did not train them by letting them handle and see counterfeit money. They trained them by letting them see and feel real money. Then when some money did not look or feel right, they investigated further. You know that's true about cars and other items that have motors. Sometimes they just don't sound right. We don't know what's wrong; but we do know that something is wrong. In the past there have been groups and probably still are that believe that we cannot fight Satan unless we know all of his black arts. In other words, we are to look at and handle the counterfeit - that is the way to defeat him. But this says that is not true. This says that if we walk in God's light then when something doesn't look or feel right we become suspicious and examine it closer. It's the "the light of one candle chases away the darkness". Continue to walk in the light of His word, and you will chase away the darkness. Father help the reader to always walk in the light of Your word. Help him/her to get closer and closer to You so that Your light chases away the darkness.
