I believe that this picture of a funnel is a wonderful reminder to receive vertically from God Who is on high and wants to pour His love and wonderful provision into our lives. All of this is available to anyone who wants to receive from Him. Alternatively we can choose to limit our vision to a horizontal scope at the world around us but it will be a poor substitute unless connected to God. 1 John 3:1 "See what great love the Father has lavished on us...".
