What you put in you is what will flow forth. What do you believe? What do you surround yourself with? What do you listen to? What do you read? Who do you fellowship with? What do you watch?
To grow in faith and be filled with more of the Spirit you must be intentional. Every day there are countless opportunities and decisions about what to fill yourself with. What you choose to put in will inevitably have a direct affect on what will come out. It is only a matter of time.
Our culture wants to act like their is no correlation. Listen to crude music, watch filthy television, surround yourself with course language - it doesn't make any difference. This isn't so. These things influence and ultimately shape our thoughts. If we put garbage in how can we expect a sweet aroma to emanate?
Each day we are each given options. Will we surround ourselves with things of God, furthering our knowledge and understanding of him; growing in our spiritual maturity? Or will we waste another golden opportunity to become more of the person God intends for us to be?
We have free will. The choice is ours. We can claim to believe the things of God and claim the salvation of his Son, but our faith will remain stagnant and our growth will be stunted if we do not choose to immerse ourselves in the things of God.
We cannot wade at the shore line or stand waist deep in the shallow end. To experience the fullness of God we must get in over our head, completely overtaken with the things of God.
