Why I cannot pray for rain, God uses drought to reminded us of how we do not obey the Word of God and the curses a dis obeying  hart brings. Drought works in conjunction with How we look into our Fathers Word to be come like Christ. When we pray for rain God does answer our prayer. But even with that answer we do not let Him deal with the condition of our heart, not stopping the cycle for the drought so the drought repeats it self and becomes worse every season. Along with the drought He also uses politics to show us how we can do nothing with out Him.  So I look at Jeremiah 29:11 on, as a place of understanding how God provides as He prepares Judgement as well  while  in Judgement . Even though according to John 3:17:18 he does not have to Judge any more. Yet it is adding to my definition  of  "looking up" in Matthew 24. This how God desires for us to "Look"  at signs and wanders in order to get our attention as well as to speak to you and me.
