John 16:13 (NKJV)
Many airports in the United States use something called Precheck. If you are given Precheck status when you are at the airport then you are able to go through a different security line than other people and the security check itself is different. With Precheck you don't have to do the same type of security check as everyone else and the whole process is much simpler and easier. Because someone did some work for you ahead of time, the trip was made smoother. All you had to do was take advantage of what was done for you previously to enjoy the benefits.
There have been times when I thought how nice it would be to have Precheck in my everyday life. Someone could check into my journey through life ahead of time, grant me special status, and then give me the information about how to go through everything simpler and easier than what might normally happen. What I found out is that as a Christian the Holy Spirit lives in me and Jesus said the Holy Spirit would show me things to come. The Holy Spirit knows what is coming into my life and He can help me be prepared for it so that I can have a sort of Precheck for life!
If we follow the direction God gives us in His Word and we learn to be led by the Holy Spirit then we can be ready before we face challenges or run into difficulties in our life. Just like the Precheck program allows someone to go through a different line than other people and makes things easier, the Holy Spirit has "prechecked" things, so to speak, to be able to guide us in our life and prepare us for things ahead. He will help us go through whatever we deal with in life in an easier way than if we tried to do things ourselves. We don't have to go through life like the rest of the world; with the Holy Spirit helping to prepare us we can be ready for anything that comes!
