'Last your burden on the Lord, and He will sustain you; He will never permit the righteous to be moved' Psalm 55:22
What does a burden look like? Does my photo of Lara with the rubbish piled on top of her help to answer that question? Maybe, maybe not.
We gather so much stuff, physically and in our minds; thoughts upon thoughts, opinions upon opinions, it can become unhealthy. Stuff of the past, dark areas of your life, etc. What does the Psalm passage say about our burden? Give it to God. People do pray, and I don't think people see it as an abstract thing. When some people are in desperate situations, I do believe they will pray or think about praying...
And God can give you peace, rest, He can carry your load. And I've witnessed this, honestly, this is the truth. Jesus says:
'Come to me, all you who are weary and burdened, and I will give you rest.'
