Read John 5
The major theme of John’s Gospel is to reveal Jesus as not only our Savior but also as the Divine Son of God who is also one with God the Father. Much of John’s writings, themes, and theology form the basis for would later be known as Trinitarian Theology. The Athanasian Creed lays this out well:
We worship one God in trinity and the Trinity in unity, neither confusing… nor dividing the divine being.
For the Father is one person, the Son is another, and the Spirit is still another.
But the deity of the Father, Son, and Holy Spirit is one, equal in glory, coeternal in majesty.
John begins to lay this foundation through Jesus’ conversation with the religious leaders. Jesus doesn’t mince words at all, talking about Himself as being equal with the Father, and especially doing the “Father’s work.” In fact, Jesus points out that He can do nothing apart from the Father.
There are some difficult sayings here too, but ones that we must take seriously. Jesus says that those who do not honor the Son do not honor the Father. In an age where many people seem to think its ok to say “we all serve the same God,” Jesus’ words add a caveat to that. Several major world religions find their roots in the Old Testament, but only through honoring Jesus as Lord do we find the true way back to the Father. Watch for more of this theme later in John.
One other thing to consider: Jesus does only what He sees the Father doing. As the body of Christ, the Church would fall into this same function. I wonder if we are focused on looking for where the Father is working so as to know what we should be doing?
