The Authenticity Of a thing is not readily known until it’s put to the test. Sure, when you declare you believe a thing, when adverse circumstances arise; if you continue to affirm the same thing, then your belief is as good as gold.
1 Peter 1:7-9
7 That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ: 8 Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory: 9 Receiving the end of your faith, even the salvation of your souls.
