It can help us when we can get a mental picture of things. Which is why we probably like to be able to see things to help us make a decision.
Some would therefore question how we can believe in God when we can’t see Him. But while God himself is not visible, his actions and his love definitely are. And it’s because of what God does for us that our faith in him grows.
2 Corinthians 5:7 (The passion translation)
For we live by faith, not by what we see with our eyes.
Who else can send us a friend or confidant when we feel alone?
Who else can give us direction when we dont know where our life is going?
Who else can confort us when we grieve, and remind us to focus on the good memories.
