James 1:3 Knowing this, that the trying of your faith worketh patience.
Recently I had chest pain like I’d never had before. I was afraid I was having a heart attack. So I went to the emergency room and they ran an EKG and blood enzymes. They found nothing but advised me to follow up with my cardiologist immediately. I did and he ordered a stress test. Then I went in to the office for the results. During the interview process he suspected it was esophageal spasms. They mimic a heart attack, right down to responding to nitro tablets.
Test result are only obtained through testing.
The testing of your faith is done to give you the test results, that your faith is not a mimic.
If you want to insist that faith cannot be mimicked, please do, but the issue of test results is not to prove you have faith, but rather where it is to be found.
Is your faith in Christ? How do you know for sure without it being tested?
Matthew 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
The deceiver will confirm your faith without testing because the last thing he wants is for you to discover you have placed your faith in a lie.
James 1:2 My brethren, count it all joy when ye fall into divers temptations;
Count it all joy that you are tested because it is a sign your faith is in Christ.
