Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. For we know in part and we prophesy in part, but when completeness comes, what is in part disappears. When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. For now we see only a reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known. And now these three remain: faith, hope and love. But the greatest of these is love. 1 cor 13:8~13
There are trials we don't know why they happened to us, we didn't deserve those, and they were totally unfair, but we must go trough in order to be tested and perfectioned in the Fruit of the Spirit :)
You cannot persevere unless there is a trial in your life. There can be no victories without battles; there can be no peaks without valleys. If you want the blessing, you must be prepared to carry the burden and fight the battle. God has to balance privileges with reponsibilities, blessings with burdens, or else you and I will become spoiled children.
