Psalm 34:8 (NKJV)
Oh, taste and see that the Lord is good; blessed is the man who trusts in Him!
I can witness, argue, persuade and otherwise plead with you to put your trust in the Lord, but there comes a point in which you must find out for yourself that He is everything the Bible says He is. You don't have to believe me, try it yourself and you will find out.
You have heard it said: "The proof of the pudding is in the eating of it." The world says, "I'll believe it when I see it." The bible says the opposite: "You will see it, when you believe it." Jesus invites us to try an experiment:
John 7:17 (NKJV)
If anyone wills to do His will, he shall know concerning the doctrine, whether it is from God or whether I speak on My own authority.
