My children did not always understand the reasons behind my answers of "no" to them. Whatever the reasoning may have been for each instance at the time, was always to ensure the best possible outcome.
Therefore, just as we must tell our own children "no' at times, our Father must do the same for the purpose of ensuring the best possible outcome for us, as well.
There were also times that I might instruct my children to do a specific task that was out of the ordinary. I can't say that my children were particularly pleased with every request as such but upon obedience their reward for a job well-done (an act of obedience) was gladly received.
Likewise, as I stated in the beginning, we may not always understand why we are being asked by the Father to do something out of the ordinary for us or we simply may not like what He's asked us to do.
The bottom line is, He always has the best outcome for us in store, whether it be protection from consequences or a reward at the end of the day. He's an extremely, extraordinarily, GOOD FATHER, therefore we can trust Him with all that we have....unto obedience in all that He asks.
