The other night at Bible study, Greg brought a message he had received as a daily word from Prison Fellowship. One passage in that letter struck me: “Paul reminds us that there is no such thing as a spiritual vacuum in life; every moment of time and every opportunity of life not seized and engaged for the cause of Christ and His Kingdom will be lost to the powers of evil and sin. (Eph. 5:15-17). This brought to mind a metaphor I’ve always used to teach young people about the Christian life.
What I always say is that life is like a river and you are a Salmon. As a believer then you must swim upstream, against the current of this world. You cannot stand still, because the current will just push you back out into the ocean of sin, worldliness and temptation. You have to fight the current in fact just to stay where you are at! And, you must work even harder to make it farther upstream towards the goal – in our case Heaven. It’s a useful analogy for teaching the concepts of the Christian life, and it is in fact based on that same principal in Ephesians 5:15-17.
