Jesus was raised in a particular time and place, and came from a particular religious background. So he used the mythological and tools avaliable to him. Some of that was the Judaism of his era, but much of it was also Egyptian and Greek mysticism. But Jesus and the traditional depiction of Yahweh have very little in common.

When Yahweh forbade mixed fabrics, it was a cultural thing to separate 'his people' from all others and to satisfy his autism. Jesus used this because he had been raised within Judaism, but he reinterpreted it for his own purposes as advice against divided loyalties or a warning against incomplete spiritual transformation. The fabric itself was almost irrelevant, but the existing rule was a useful tool for communicating a truth he had encountered. It is similar to how Socrates and Plato superficially invoked the gods of traditional Greek religion, but through their philosophy it becomes clear they did not approve of their depictions in said tradition and were essentially talking about different entities altogether. Some disciples understood this (physical circumcision versus circumcision of the heart) and others did not understand at all. 

Jesus very directly inverted Old Testament morality all the time, which is why the religious authorities of his time hated him and why modern Judaism considers him an apostate. Compare the treatment of the man who collected sticks on the Sabbath, versus Jesus almost being killed because he healed on the Sabbath. For him, the Sabbath as an imposed set of arbitrary obligations made no sense if the purpose of a Sabbath was rest, so he didn't observe the rules but rather the underlying spirit. That's what matters.

Jesus wouldn't care what you call his Father, as long as the entity you call his Father is in fact his Father and you do his will. Whether the writers of the Old Testament misinterperteded the true nature of Yahweh, or if Yahweh is the evil Demiurge of the Sethians, or if Yahweh never existed but was a convenient cultural tool for Jesus to begin explaining the Father, is almost irrelevant.
