Why is Jesus referred to as the Word? A “word” is a communication of intellect, it is the audible expression of an inaudible thought. We, as humans, could never know the heart and mind of God, until He sent His Word to live among us.
For our physical health, we need an annual exam just to check us over and make sure everything is okay. Generally, it's not the things that are on the surface that the doctor is looking for - there are little signs and under-the-surface things that are small now, but may become big later. For our spiritual health, we need even more regular examinations.
If you are sick, you’re not going to get any better by only treating your symptoms. You have to treat the problem at the source. If you’re lost in sin, you’re not going to get any better by trying to change your actions. You have to let Jesus transform your heart and mind and tackle the problem at the source.
The church is not helping the world by pointing out sin. If we want to help the world, we have to lead them to God, the only one who can fix the source of the problem.
Scripture used: John 8
