The question is what is this plan? I believe there are two elements to this plan and purpose:
1. The overall plan.
This is a plan that is common to each and every one of us. The overall plan is that we would know God.
Acts 17:27-28 So that they should seek God, in the hope that they might feel after Him and find Him, although He is not far from each one of us. For in Him we live and move and have our being.
We need to discover that we are nothing without God. That we can seek Him and find Him. The promise is that He is not far off.
The specific and particular race He designed and intended for each individual to run. This is unique and individual to each person. I believe that this element flows out of the first element.
As we seek God and go after Him, He reveals to us what He wants to do. It is like something we have to discover! It is an exciting voyage of discovery. This He does in a step by step process as we give Him first place in our lives!
God for it! God is ready to fulfill your redemptive purpose!
