It's a natural, because it's an apple tree. The fruit of the Spirit is also a natural by-product of the indwelling presence of God in your life. An apple tree needs some pruning or fertilizing and some special attention, but the production of apples is its natural inclination. The fruit of the Spirit is not something you can produce. You may achieve a measure of success in each of these area on your own, but you can never experience them in fullest measure apart from Christ and the indwelling of the Spirit of God.
Some people seem to experience greater power, greater fruit and greater results.
Because of this, we sometimes see God's power manifested differently in each other. We will not see, however, some people having more Holy Spirit than others. There are two key ingredients that foster the full manifestation of God's power in our lives. The more we give up to God, the more God gives to us to be all that He designed us to be. Our failure to surrender quenches the Spirit in our life.
