There are those who, like myself, have many spiritual fathers and mothers but not in a structured or formal way, with saints who like us realise that there is only One teacher, the Messiah (cf. Matthew 23:8-12), and would not allow us to pedestalize them. I am the same way. I sometimes am spiritual father to someone, and then we switch places the next moment. How is this? Because Christ who is alive and among us at this very moment is, as He says, the only Teacher. We only say what we hear Him saying.
My dear people, we are already the children of God
but what we are to be in the future has not yet been revealed;
all we know is, that when it is revealed
we shall be like Him
because we shall see Him as He really is.
1 John 3:2
I take the verse quite literally. Seeing Christ at His glorious coming will perfect us into the image of His holiness and His eternity, and that, whether we were hard on ourselves or easy, as long as we believe in Him. The part about trying to purify oneself, as He is pure, is just the work that He has given us to do, while we await His return. He knows that we cannot finish the job. He knows that even with His grace, our old man will not be completely burned up until we see the light of His face. He knows who is fooling Him, even though they are mighty in works and self-discipline. He knows who is following Him, even though their performance may not be spectacular. He knows everything about us, and He doesn't judge those whom He has redeemed, because everyone is judged by the Word He has spoken to each. Will our consciences condemn us before the Lord? That is the question.
Surely, everyone who entertains this hope
must purify himself, must try to be as pure as Christ.
1 John 3:3
Try to be pure as He is pure? What else is there to do? Be changed into His likeness at His second and glorious coming? How can we not be, if we have confessed Him before men?
