As you develop the ability to draw near to God through prayer, meditation and scripture memorization, you gradually undergo a fundamental shift in your values. Without a positive shift in your values, you will not have a permanent shift in your character. Removing the stain of sin from our hands builds character. In both scripture and poetry our hands are the physical expression of our spirit. Our hands are the point of contact we have with others.
Hands are the practical expression of our relationships.
In our defective, negative attachments, we manipulate, use and often abuse relationships for our own selfish purposes. We can be like blood suckers in the negative way we attach ourselves to others. Use your hands to relate to people in a positive way if you wish to get rid of defective character traits. Purifying our motives is a process that builds character. This is talking about the role of motivation in character development.
