The movement may be almost imperceptible at first, but over time it will become clear that their relationship with Christ is being affected. I've seen this happen over and over again when I worked with youth. Young people often put a lot of time, money and effort into following their favorite groups. All this adds up, piece by piece, pound by pound. Eventually it tips the scales in their Christian walk.
Some people claim they have a balanced Christian life.
Their teeter-totter isn't tilting in either direction. Their Christian activities are perfectly balanced with the negative philosophies they entertain themselves with. But let me point out that a level board on the spiritual teeter-totter is not a sign of a healthy Christian life. The goal is to have the scales tipping completely toward Christ. This is a life that is neither hot nor cold.
