Whatever your idea of truth is, you identify with it, think it is your self, will protect it, defend it, want it, believe in it, have faith in it, see it as real and love it above all else. It doesn't matter whether it is actually true or not in the bigger picture.
It's good when your idea of truth matches God's truth because this actually brings you closer to life and to health and happiness.
But when your idea of truth is mistaken and you believe something is true which is not, you will STILL defend it to the death, and take sides against life. This will result in you becoming sick and disconnected from life, and eventually to die.
This happens because you are choosing death (the belief that what is false is true) but are believing you are choosing life, because you are confused about what is true and what is false. The ego always tells you that if you choose its thought system you are choosing the truth. But when you actually listen to it and choose it, you are choosing to believe lies. And this will tempt you away from God and towards death. You will then experience unexpected consequences and suffering, because the ego's advice does not work and results in the opposite of what it claims.
When you are insane and delusional like this, believing that something is true that isn't, you will be heavily in denial and unwilling to accept the real truth. You will become unaware that you are hurting yourself and making yourself suffer with your defense of lies. You'll think you are saving your life by defending yourself against God's truth, which you now perceive as false and opposite and an enemy.
If you want to experience life and not death, you must choose to align your idea of TRUTH with God's truth, in recognition that only the truth is true. It is your choice which voice you listen to. Either you choose life by choosing to believe God's truth, or you choose death by choosing to believe ego's truth. Either way it is CHOSEN.
"No one dies without their own consent." "You cannot die unless you choose to do so." "You cannot be hurt unless you hurt yourself." Secret of salvation - you're doing this to yourself. There are no limits on mind other than that it cannot serve two masters - you must choose, whether you place your faith in death, or whether to place your faith in life. Faith in God is believing God and trusting God and accepting God's will. This literally resurrects you from the dead (fake death) and restores you to awareness of your immortality. Not even death can prevail against a Son of God who has commended his spirit into God's hands.
