The amount of time you're willing to invest and the horse's personality or history will impact how long it takes you to bond with a horse. The more time you spend getting to know the horse, the more likely you will connect with them.  It may take longer if you're working with a very stubborn horse or a horse that has a history of abuse. Never underestimate the power of a single session with your horse, though.  Even simply introducing yourself to the horse, spending some time with them, and being confident and forceful can have an immediate effect. With just a few minutes of preparation, respect may be earned. Giving lots of praise for obedience helps reinforce a good bond.
