Don't believe everything you think.
Chemicals don't think.
What makes up a person is their mind, will and emotions. It's easy to spot people who are out of balance: someone who is too intellectual is letting what they think about rule them. Someone who is all drive will trample over people to get their way. Someone who is all emotional will give full vent to their rage.
Why give control over your life to anything?
Why sit there until you die?
If you remain where you are, you must perish.
If you go to Jesus you will live. If you sit in sullen dispair no one can pity you when your ruin comes; but if you were to die SEEKING MERCY (as IF that were possible) you would be the object of universal sympathy.
You know others who were saved by believing in Him (your own friends and neighbors); so why not you? Why not taste and see that the Lord is merciful?
To perish is awful. We assure that if you seek Him, you will find Him, for He casts out none who come to Him. You shall not perish if you trust Him. On the contrary; you shall find treasure; eternal treasure, that will be stored up for you beyond this life.
We preach to the living even where the vultures gather because we must. Because we know the truth, and the truth will set you free. Because we too were about to perish when we got up and sought mercy for ourselves. We preach because God has ordained us to do just that. A sacred responsibility.
