There are wars which are waged quietly. Fights that are not discussed, never posted about on social media, or on prayer lists. We smile in the presence of others, while burdened with pain in our hearts, sometimes. When everything in us is screaming, “I need help!”, we answer, “I'm fine.” However, there is one Person who can see past the smile, understand the unsaid word, and know all the battles that we are facing: God.
God is aware of your secret battles. He does know the nights that you lie awake, thinking of your problems. He is familiar with the tears you have to wipe away before others see them. He understands what you have lost behind a smile and what you've feared and can't tell anybody about. There is nothing hidden from Him in your life.
You may feel like nobody cares or understands what you're going through, which is normal at times. Others may not realize you're in pain. People in the family may not be aware about how much weight you're carrying. Your fellow family members and friends may never be able to comprehend your difficulties. But God does.
When we feel lonely and afflicted, we can turn to the psalms to see in Psalm 34:18 that the Lord is near the brokenhearted. That is, when you are feeling at your weakest, God is not far away. If you don't know the words for your pain, He speaks the language of your heart.
Perhaps you are fighting a battle concerning your future. Perhaps you are dealing with a lack of money, emotional, spiritual or personal support. Perhaps you're asking for something that really doesn't seem to come soon enough. You may even be questioning whether God still remembers you.
He does.
God does not turn his back on you if he hasn't answered your prayer. There's no need to worry that your story is dead because you're tardy. At times, God is at work where you are not looking and preparing what you don't yet understand.
Keep in mind some of the best years in life start on the toughest roads. Before David was king, he fought battles. Joseph suffered injustice and jail time to find out what God had in mind for him! Jesus suffered even before he rose again.
Therefore, don't be embarrassed of the struggle you face. You might be tired, but you're still on your feet. You've cried lots of tears, you're still believing. You don't have to know it all, but God is still holding you!
There is no need to tell things to everyone. Some battles, only God knows about. Take your worries to Him. Share your fears, disappointments, dreams, and unanswered questions with Him.
If you don't have anyone to talk to, talk to God!
If you are weak, then lean on Him.
When you don't see how to do something, believe He can do it.
One day you will look back and see that season that you thought would break you has made you stronger. Your tears were not in vain. You prayed in silence and your prayers were answered. The battles you fought in secret, were preparing you for a victory that will speak out.
God is aware of your fight. God is mindful of your tears. God knows the desires of your heart. God isn't done yet with your story. Keep trusting Him. You can still have a strong testimony despite your silent struggle.
