"When you pass through the waters, I will be with you; and through the rivers, they shall not overwhelm you; when you walk through fire you shall not be burned, and the flame shall not consume you" Isaiah 43:2
God has promised trials for His children. There is no escaping with this fact. Sometimes, it is through deep waters or rivers and sometimes you are called to walk through fire! If you read the verse carefully, it says 'pass' and 'walk'. There is no sense of hurry or impatience; slowly one step at a time!
But, look at what God has to say, "I will be with you". That is His promise. He has promised to be present in our deepest afflictions. And no matter, how hard our trials, God will not give more than we can bear. He is compassionate!!
Look at the verse, "When you walk through fire you shall not be burned, and the flame shall not consume you." (emphasis mine!)
God is faithful in all His words and kind in all His works. (Psalms 145:13)
