The LORD is Good
“The LORD is good, a refuge in times of trouble. He cares for those who trust in him,” Nahum 1:7
To trust someone you have to really know them. Knowing someone goes beyond marginal interaction. Knowing someone is having inside information, as in an awareness of who they are through time spent, talking with them, sharing with them, and they in turn sharing with you.
Trusting God also requires spending time with Him, getting to know Him. As you spend time in His presence a relationship with Him is developed. And when you realize He is good, unchanging, and filled with grace and mercy you will come to know that you can trust in Him. The Lord is good (also see Lamentations 3:25-26), a refuge in times of trouble!
