I encourage even the skeptics to listen to this music video. The least you can come away with is having looked at some illuminated manuscripts and having heard some great Celtic-style music that will make you want to dance!
But you may hear the words and want to know more about this Lion of Judah who takes away sin and guilt and puts joy and peace in their place. In that case, read through the book of John in the Bible. This is God in the flesh, Jesus, having come to Earth to pay the penalty for our sin and suffer the wrath of God poured out on Him in our place. When we put our trust in Him, we get His righteousness poured out on us so that no matter what our past looks like, we can stand guiltless before God and live every day with hope.
So how do we 'put our trust in Him' when we don't understand everything about everything? Putting is an act of volition - the will. What some people call faith is simply emotion. They have the utmost 'faith' when everything is going great in their lives. But when the chips are down, their 'faith' disappears. Why is that? Maybe they've been confusing faith with feelings and have been relying upon a feeling. When we come upon the rough times in our lives, feelings are not reliable and happiness is elusive. It's not easy to feign happiness during the tough times - like the death of a loved one, or divorce, or sickness, or betrayal, or financial ruin, etc.
But real faith is the act of Putting (it's an action verb) our trust in Christ - even in the darkest moments when we cannot see even a speck of light at the end of the tunnel.
So keep putting. Jesus, the Lion of Judah, always meets us there. He's the only One worthy of our trust.
Have a blessed Lord's Day!
