'O Jacob, how can you say the Lord does not see your troubles? O Israel, how can you say God ignores your rights?' Isaiah 40:27
We grow disgruntled with troubles because we think God either doesn't see them or doesn't hear us when we pray.
How would we feel if one of our own children grew disgruntled because we didn't sort their difficulties? Sometimes, there is a plan, a bigger picture, that we cannot see at present. The faithful child continues to trust the Father and wait for the appointed moment.
Even when it appears that God does not answer our prayers we must learn that He hears our cry and understands the unsettledness within us. Take the fear and bring it to Him. Discover the strength of His arms, the safety of that hidden place in Him. Your prayer may well be answered positively, but for now, learn to rest in those strong arms that hold the world together. The sound of the 'heartbeat' of God is enough to still the complaining soul. He is with you. Be not troubled. He understands.
'No one can measure the depths of his understanding.' Isaiah 40:28
