Engaging in self-sacrificing work for others strengthens character and avoids the spiritual stagnation that comes from self-absorption.

Original passage

Nothing will so arouse a self-sacrificing zeal and broaden and strengthen the character as to engage in work for others. Many professed Christians, in seeking church relationship, think only of themselves. They wish to enjoy church fellowship and pastoral care. They become members of large and prosperous churches, and are content to do little for others. In this way they are robbing themselves of the most precious blessings. Many would be greatly benefited by sacrificing their pleasant, ease-conducing associations. They need to go where their energies will be called out in Christian work and they can learn to bear responsibilities.
