Before the end, have your will changed, after the end, there is no changing it.
My world ended when my conversion back home to my Lord began way back in 1998. The life I was leading is gone. The “worldly” ambitious dreams I had are gone. The false peace, is gone! The life I wanted is nothing I want now. I can only keep focused on the life after this one, WITH Him. I can only prepare for the day He comes and there is absolutely no strain to do so. It brings me only joy to do it and to ponder it. It is a total pursuit of holiness now because I am now yoked to Him and not to selfish ambition. Its He doing all the work and I am following His lead. It is living because I love Him. It is accepting the suffering through this life, because His suffering is now mine. My will, is that His will be done. It is doing everything for Him, not because He has done everything for me, but because the love is pure and nothing like it has ever come close to me in this world as His love has. He is all I want. He is all I have and with Him, I have everything.
With all the talk about the mayan end of the world, all I can say is: “No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father.” Matthew 24:36
This is not to say, He wont be back. He will. The question is not when but rather, are you going to be ready? Are you going to change your will? Will you give Him everything? I do.
