Hebrews 11:1-3 Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report. Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
A person can go through just about anything if they have the Lord with them. Faith will literally allow you to hold in your hand things that have never been seen.
Those who see Jesus ---The Invisible God--- know that the end of their faith justifies the journey.
