What I am doing you do not understand now,but you will know after this. 

You shall remember that the Lord your God led you all the way these forty years in the wilderness, to humble you and test you, to know what was in your heart, whether you would keep His commandments or not.“When I passed by you again and looked upon you, indeed your time was the time of love. Yes, I swore an oath to you and entered into a covenant with you, and you became Mine,” says the Lord God. § Whom the Lord loves He chastens.Beloved, do not think it strange concerning the fiery trial which is to try you, as though some strange thing happened to you; but rejoice to the extent that you partake of Christ’s sufferings, that when His glory is revealed, you may also be glad with exceeding joy. § Our light affliction, which is but for a moment, is working for us a far more exceeding and eternal weight of glory, while we do not look at the things which are seen, but at the things which are not seen.
