Romans 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
I hope this will, maybe in part, answer the question about how to "school" our feelings, which, in my opinion, is just channelling thoughts and feelings into a profitable direction. It means to be calmly assured, rather than restless, discontent, upset. It does not come naturally to everyone. A lot of people are very susceptible to suggestion, and their emotions are tuned into just about everything that happens or might happen. Feelings have to be guarded and trained. For example, there are some times you might not feel like making lunch, but you have others to think about and they depend on you to make lunch, so you overcome your feelings and do what is best for them. When we are transformed, we no longer allow the world and those around us to control our lives, but we do the controlling, guided by the heavenly principles written for us.
Renewing the mind can do many things: it can make the cloudy, dark weather seem inconsequential, as we busy ourselves doing what needs to be done. Renewing the mind can make life richer, just by focusing on what is good. Now and then, someone is going to make a rude remark that will make you feel worthless, but you can endure it by substituting worthwhile activity. Clean a drawer, catch up on correspondence, do some hand work, and foremost of all, fix yourself up as though you are on top of the world. It can enable a person to use the worst circumstances as a step to something good. When our grandmothers had disappointments, they immediately went in the house and swept the floor, washed the dishes, and made dinner. Since the hands engage the mind, something far healthier happens by making things better, than by allowing fears and worries to guide you.
Conforming to the world also means that we feel controlled by today's fashions,news,music, education, and even by the current personal relationship trends. It is a never-ending cycle of keeping up with everything. The solution is to stick with something you love, whether it be a style of decorating, the reading you like, clothing, cooking, or the type of outings you enjoy, and let the world and its trends pass on by. You won't miss the stress of constant change.
The Bible says that we aren't to be conformed by all that the world is beckoning us to , but to prove what is the good and acceptable will of God. You aren't going to prove the beautiful , God-given role of women in the home if you spend the day upset and worrying. You will prove it if you do not waste time trying to conform to the world's dictates, while giving your home your very best.
I've always believed in substituting a "yes" for a "no." When my mind wants to dwell on bad news, I substitute a favorite hymn or scripture. Each time a plaguing thought comes to your head, sing that song or quote that scripture, even if it happens all day long. It will school the mind and bring something productive and positive into your life.
Here is a verse I like :
Isaiah 26:3 "Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. "
