What do we reap when we follow the desires of our flesh and soul?...

Spiritual death—the loss of the Presence and fellowship of God in Christ.

There is no more effective way to lose the Presence and fellowship of God than to follow the desires of the flesh and soul, keeping busy with the things of the world—houses, furnishings, vehicles, properties, money, clothes, employment, entertainment, travel, leaving little time for prayer, studying the Scriptures, or having fellowship with fervent disciples. While these are not necessarily sin they cause us to neglect our salvation and therefore destroy our spiritual life.
