O taste and see that the Lord is good; How blessed is the man who takes refuge in Him!
Psalms 34:8 NASB
What makes God so good is that He is trustworthy. Whatever God says you can take it to the bank. The way we get to see His goodness is to take refuge in Him. The way you do that is to dwell in His word. Dont rush reading the bible but let it digest in your soul. Let His good word melt in your heart to build faith in Him.
