Faith
God expects us to use our minds (Matthew 22:36-38; John 8:32) We do not have to commit "intellectual suicide" in order to have faith. A weak faith is the result of our hearts trying to believe what our minds reject.
Does this mean we can have 100% proof? No, but we often commit 100% with less than 100% proof. I.e., When we fly on an airplane (we do not have a 100% guarantee, but we commit 100% anyway). Why? Because the safety of commercial aviation makes it a rational, intelligent decision Now, we must ask ourselves, "Is there enough evidence for me to make a 100% commitment to Christ?" I believe there is...
a. Certainly there is enough to commit myself 100% for Him, rather than be 100% against Him!
b. There is no other alternative (Matthew 12:30)
“He who is not with Me is against Me; and he who does not gather with Me scatters.” (Matthew 12:30, NASB95)
The Christian faith is based on making a rational, intelligent decision.
