Whatever a man sows that shall he also reap
All of life is sowing. Our words are seeds, our actions are also seeds. Even our all your passivity or inactions are also seeds.
So, everyday of your life, you are either sowing into the flesh or sowing into the spirit. One way to sow into the spirit is make use of every opportunity to do that which is good towards all men, especially towards them that are of the household of faith.
