He brings us to a position of faith and trust through our experiences with Him. My life - and that of my parents before me - is full of stories of His faithfulness in times of trouble. We will have trouble. That is the nature of life on earth. It is through trouble that we get to know God and to discover that He is 100% trustworthy. Circumstances are immaterial.
Upon carefully reading scripture on the subject of trust, it's interesting to discover that trust is often linked with witnessing to others through the rough time! It seems to be the case that when we tell others during the difficult time - or afterward - that witness to the Lord's faithfulness is honored and rewarded by a continual increase in our faith and trust. It seems to be a spiritual principle. Joy and praise are always integrally linked to faith and trust, too.
We learn through walking with the Lord that His wisdom is infinite, He always knows what is best for us, and His judgments are perfect. Although things may not make sense at the time of the awful circumstances, we can often (though not always) look back and see that He has performed miracles - miracles which we would have missed had we not trusted His perfect will and wisdom.
God is sovereign. He is able to accomplish anything at all. He is the essence of truth and love and wisdom. Nothing stands in His way. Everything that happens occurs with His divine approval OR permission. He is in absolute and complete control at all times.
