It needs action
Do you wash the dishes and just let all the bits and pieces go down the drain ?
Perhaps a bit of food or a little piece of paper.
Fat and grease from a plate ?
They all go down the drain, but in time they build up and build up until eventually they block the drain.
Now when you pour water down the drain it comes back up again because it can't flow away.
There is a blockage.
Sometimes we can have spiritual blockages.
We keep doing things wrong, all the time we do the wrong thing and they cause a blockage between our communication with God.
A spiritual blockage needs repentance.
Confess your sin to God so that he can clear it away.
When sin is confessed then the blockage is removed and communication can be restored.
God wants to have a relationship with us but he is holy so sin can easily get in the way and block the communication between us and God.
Keep your account short before God and keep your communication open.
