He often speaks to us through other people. But when we see their defects or doubt whether they are well informed — whether they have grasped all the aspects of the problem — we feel inclined to disobey.
All this may have a divine meaning, for God does not impose a blind obedience on us. He wants us to obey intelligently, and we have to feel responsible for helping others with the intelligence we do have. But let's be sincere with ourselves: let's examine, in every case, whether it is love for the truth which moves us or selfishness and attachment to our own judgment. When our ideas separate us from other people, when they weaken our communion, our unity with our brothers, it is a sure sign that we are not doing what God wants.
Let's not forget: we need humility if we are to obey. Look again at the example Christ gives us: he obeys Joseph and Mary. God has come to the world to obey, and to obey creatures. Admittedly they are two very perfect creatures: Holy Mary, our mother, greater than whom God alone; and that most chaste man Joseph. But they are only creatures, and yet Jesus, who is God, obeyed them. We have to love God so as to love his will and desire to respond to his calls. They come to us through the duties of our ordinary life: duties of state, profession, work, family, social life, our own and other people's difficulties, friendship, eagerness to do what is right and just.(Christ is passing by, 17)
