I have a friend who was ready and excited to have a fourth child. However, her husband was hesitant, he was perfectly content with their three girls. They didn't let the situation escalate, instead, they stopped and prayed together and independently asking God what was in His will for their family. My friend was sure that God would change the heart of her husband so they could have another child. But after committing to prayer and trusting God for the answer, she found it was her heart that was changed. She found herself satisfied with her children and new it was time to be content with the blessings God had already given them. You see, she knew in her heart that God was working in the lives of her family. Her answer wasn't what she expected, but God did give her an answer, even though that answer is sometimes a "no." However, God was walking with her and helping her through this struggle of her heart.
A lot of times when we ask God for help we think we know what will make the situation better, we just wait in anticipation for it to manifest. However, what we don't see is the greater perspective, God's eternal perspective. God has a purpose for all of us, we simply have to trust Him to work in us and in those around us.
By committing to the Lord and trusting in His purpose for us, we allow Him to do miraculous things in and through us.
