John 5:19
19Jesus therefore answered them, “Most certainly, I tell you, the Son can do nothing of himself, but what he sees the Father doing. For whatever things he does, these the Son also does likewise.
Nothing of his own accord is not inferiority. Wesley: it is the Son’s glory—eternal, intimate, indissoluble unity with the Father. The Son does not freelance; he perfectly images the Father’s will. That unity is the ground of our trust: the One who heals and calls us does the Father’s own good.
The Son’s inability to act independently is not a defect in deity but the distinction of persons in one work. Whatever the Father does, the Son does likewise—one operation. The Sabbath healing was not a man’s project; it was the Father’s work in the Son.
