This week's parshah begins with a choice between blessing and curse, between obeying Hashem's commands and turning away from the Torah path. Hashem gives us that choice and trusts us to choose well. To this day Hashem trusts us with these choices, and we are constantly being given opportunities to embrace Torah and life.
The tzaddik R' Moshe Pshevorsker ztz"l explains this by pointing to the example of a master and slave where the relationship is not one of trust. Although the normal practice is for a master to lead and a slave to follow behind, if the master fears that the slave could run away, he will tell him to walk first so he can keep an eye on him. Only if he trusts the slave will he allow him to walk behind him.
So too should it be in our relationship with Hashem. Hashem shouldn't have to hold a stick over our heads in order to ensure our compliance. He should be able to trust us to remain loyal Yidden, which is why He allows us to choose, and trusts that we will willingly make the right choices.
Similarly, the Torah teaches that in a marriage, the husband leads and the wife follows. This too implies a great deal of trust between them. The husband should be secure in the knowledge that his wife is loyal, so much so that he allows her to walk behind, allowing her a great deal of freedom within the boundaries of their shalom bayis. Both spouses need to find the right balance, avoiding the extremes of obstinate independence and inflexible control.
