Well, my life span was extended twice, as best I can tell, from 2 instances where death was likely, a miraculous save. But that's not actually the verifiable evidence I was referring to. The thing that can be tested and verified for results is putting Christ's instructions into practice right now, and seeing if you life improves, right now, within months. Your absolute quality of existence, life, here and now.
Here's a very specific testable instruction past the ones I've already told you:
28“Come to me, all you who are weary and burdened, and I will give you rest.
29Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls.
30For my yoke is easy and my burden is light.”
This is quite clear -- those who are weary and burdened in life, stressed, if they will truly come to Christ in faith and learn from Him and do as He says, they will find rest for their souls now, here, in this life.
They find peace and rest even during the storms of life.
