The writer of Psalm 77 was feeling that same way. He cried for help. He couldn't be comforted. He felt rejected by God.
7 “Will the Lord reject forever? Will he never show his favor again? 8 Has his unfailing love vanished forever? Has his promise failed for all time? 9 Has God forgotten to be merciful? Has he in anger withheld his compassion?”
He was really in a bad place.
But look what he did. He remembered.
He remembered what God had done in the past.
11 I will remember the deeds of the LORD; yes, I will remember your miracles of long ago. 12 I will consider all your works and meditate on all your mighty deeds.”
For some reason we have really short memories when it comes to what God has done for us and really long memories of the bad things that happen to us. We need to consciously work on reversing that.
How much worry could you avoid if you remembered how God had cared for you in the past? Would you live your life differently - like without fear or sorrow - if you remembered how God had answered your prayers in the past? Could you... well....ask your own question about something that keeps you from living Jesus' words in John 10:10 "I have come that they may have life, and have it to the full." Would remembering how great God is and what He has done in the past answer that question?
Perhaps you could keep a list of things in the back of your Bible - a list of answers to prayer, times God took care of you in difficult times, times that He showed you the right path to take.... those kinds of things. Then the next time you're all worried or feel like God has abandoned you or turned against you, go through your list and remember all that God has done for you.
Remembering what God has done for you will get you through the difficult times of life.
