God wants us to know today that He is going to do what He said He would do. He is coming, yet He is not taken seriously—instead He is being mocked. Mocked? Yes mocked.
2 Peter 3:3 To begin with, you must know and understand this, that scoffers (mockers) will come in the last days with scoffing, [people who] walk after their own fleshly desires. 4 And say, Where is the promise of His coming? For since the forefathers fell asleep, all things have continued exactly as they did from the beginning of creation. AMPC
Not only do many say where is the promise of His coming —as If He is not coming, but they live that mockery.
Maybe you are not saying it with your mouth, but you are saying it by how you live. If you are not saying it with your mouth but you are living as if He is not coming, you are mocking Him.
That's it—if we are living it then we believe it!
It doesn't matter when He is coming —but what matters is we live like He is coming, and like He is coming tomorrow. If you can see it in your heart, you will see it with your eyes and it will change how you live.
Thus, whether you say it with your mouth or with your motives, you are saying it. That is mockery—you are mocking Him. What you believe in your heart will manifest in your life (a quote from Jesus). Saying Jesus isn't coming is mocking Him and living like He isn't, is mocking Him. Mocking Him is laughing at Him, belittling Him, and even calling Him a liar.
Not only are you jeering Him if you are not living in the promise, but you are a hypocrite. You are like a Pharisees —an antichrist. What is an antichrist? A person or force opposing Christ.
