In Western culture, we are not trained to be patient. We get irritated just waiting for the computer to boot up. We are also impatient with people who don’t operate on our time table. Or waitresses who bring us the wrong order. And yet, patience is one of the traits of love. To be loving is to be patient. In a nutshell: patience is accepting the imperfections of others.
Patience begins by recognizing that people are not machines. They have thoughts, feelings, and they make decisions. Those decisions do not always please us, but we must give them the same freedom that God gives them. To condemn your son for not going to college will not have a positive effect on his life. Step back, and give him freedom to be human.
