A remark I heard this week seemed to stick. It was something to the effect that the new nature given from above is designed to work in real-life people situations. Sounds really simple and seems to demand a "duh!" More than academic study and more than emotional highs, Christianity deals with all the pressures and events we encounter daily. More than mere teaching, it is the person of Jesus Christ himself, alive and actively at work in us.
We can grasp the truths of Scripture but still fail to see that the very life situations we face the next day are ordained to demonstrate how wonderfully they operate. The problem is, the very situations that can reveal His work are usually missed as we fail to see the events for what they are - opportunities to see Christ's work.
We agree on paper that He is at work, but tend to miss the connection when encountering every item on the day's agenda, especially when there are frustrations, disappointments, pressures, and people. If it weren't for all of those, the Christian life would be ideal. But it is ideal, because He uses all of the above for good to reveal his purposes in them. His Word works.
