Pursue, chase after. In order to not pursue we must attain, we must catch. Do we ever really attain? Sure. We get titles. Sure we buy stuff. In a hundred years, those titles and stuff will no longer be ours.
We need to pursue the good things in life. Love. Forgiveness. Self-control. Once the fruits of the spirit are within our grasp, we hold on to them as long as we seek The Holy Spirit.
We fall. We fail. But we get up and re-pursue. That which was grasped once before can be pursued and attained again. The question to answer is are we pursuing the proper things? If it is good, pure and merciful it is good. If it is of The Holy Spirit, it is good and can be well with our soul.
