He called me at 4, and 10 years later at 14 my Christian mother died, and my unsaved father became a full blown alcoholic. Dad gave me to an abusive relative a year later. He kept my 11 year old sister till he sent her away too, to live in a boarding house at the age of 14 for strangers to raise. It didn't go well.
I learned to trust God in the middle of the pain. I learned to trust Him even more as He brought me thru many more challenges over the years.
In it all, I've learned to know Christ and to trust Him more and more. The valleys are more precious because I've grown to know and trust God in those hard times. He truly is a very present help in times of trouble. The mountain tops are wonderful but I've gained far more in the valleys.
Philippians 3:10 that I may know Him and the power of His resurrection, and the fellowship of His sufferings, being conformed to His death,
Getting to know Him happens more in those valleys. But there's even more gain in those valleys. A benefit we give to others. The valleys are so worth it.
2 Corinthians 1:3-5
3 Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort,
4 who comforts us in all our affliction so that we will be able to comfort those who are in any affliction with the comfort with which we ourselves are comforted by God.
5 For just as the sufferings of Christ are ours in abundance, so also our comfort is abundant through Christ.
