Even in great distressing situations God does not always immediately answer.
Leaving that place, Jesus withdrew to the region of Tyre and Sidon. A Canaanite woman from that vicinity came to him, crying out, “Lord, Son of David, have mercy on me! My daughter is demon-possessed and suffering terribly.” Jesus did not answer a word. So his disciples came to him and urged him, “Send her away, for she keeps crying out after us.” (Mathew 15:21-23).
Yet in this case the silence was only used to bring out the great faith of the inquirer. Is it not possible that God does the same thing with us but over a longer period with less distressing situations? Job 19:7 seems to say the affirmative to this question but again his position was very distressing. What about David who struggled so deeply with this issue as a type of Messiah:
My God, my God, why have you forsaken me? Why are you so far from saving me, so far from my cries of anguish? My God, I cry out by day, but you do not answer, by night, but I find no rest. (NIV Psalm 22:1-2)
But in day-to-day worries, I think God usually answers by lifting our cares away and giving us wisdom:
Cast all your anxiety on him because he cares for you. (NIV 1 Peter 5:7)
When it comes to the details obviously God does not lead a person to decide if it God’s will to brush his teeth, or other detail like that. God’s will is very wide open; he may even leave your career to you. To marry, or not to marry, is even your choice. The Bible is filled with ‘God’s perfect and detailed will’ and it is very hard for us to live it. ‘Love your neighbor as yourself’. He wants us to use our 'brains' in devotion to the service of others in love. Is there any other ‘will’ of God? Do we really need to seek Him in prayer to find out what that is?
Having said this I am very insecure about a lot of things without at least making a quick prayer before proceeding. I have made too many mistakes saying things, I wish I had not! I even pray before sending emails at work, as I often get caught up in the flesh and need to check my attitude before responding to politics.
