The heart of temptation is desire. Our desires can be triggered in many ways. Ways we must not tread on unless those desires are for God and His purposes.
Sometimes focus can be misplaced. If we set our sights on what is in front, we will lose out on what is ahead. If we spend too much time on what is ahead, we will lose out on what is in front.
We all at some point in time hoped for something. A child, a marriage, a career. You know exactly what that hope is. When the hope is finally manifested it brings forth such a harvest of joy and fulfillment. This is what a manifested hope produces.
