Being thankful for the difficult times: a long time to learn, helps to admit with others that when things go well, we forget God; and when we need His help in trouble, we turn to Him. There is even this in the beginning of marriage, effortless learning to Love in the first year, the relationship developing of its own accord. Why does the trouble prophesied come? Paul foretold that those who get married will have trouble in the flesh (self life) and he tells why. We lose sight of the Lord in the comfort of marriage and the relationship begins to fall apart. Thankfully God set eternity in our heart so that controlled by desire does not satisfy and whether married or single we are vulnerable to temptation. What is left out? "That you love one another as I have Loved you; that you also Love one another," is an inner journey to the resurrection, not to a treasure in this life. Neither can we expect others to make the journey with us, no more than we could expect someone we love to Love us in return: others are not on that journey, neither can others make this journey. The Journey is the relationship of Jesus in constant fellowship with the Father: giving His life for us the inheritance of His will. The journey is for the disciple, having "forsaken everyone and everything and his own life," forsaking our own life, because we would not make the journey unless carried by the Holy Spirit: John 21:18. If we could make the journey we would not need His help to rise from the dead and would be able to fulfil the old testament law.
