To illustrate the idea of being drawn to God, I've thought of the image of bugs being drawn to a light. However, there are some problems with that picture. That instinct can lead to the bug's death when they are drawn to a "zapper" or get too close to a candle. In addition, the light does no work to draw the bug. The bug puts forth all the effort in being drawn. In the image of "hauling" fish, the fish do nothing. It is the fishermen who do all the work.

Some other images I've used: the spaceship Enterprise's tractor beam dragging a disabled ship farm tractors dragging implements Peterbuilts (Peterbuilt just sounds more biblical than Mack truck, although White trucks could be connected to biblical or spiritual themes) pulling a trailer

God is like a Peterbuilt / tractor / spaceship and we are like the trailer / implement / disabled ship. God hooks up to us and pulls us to Jesus, where Jesus promises to raise us up on the last day. Without the power of the tractor, the trailer goes nowhere. Without the power of God, we are helpless to come to Jesus.
