If you go around complaining, does that mean that you don't appreciate that Jesus gave His life for you, so you could have eternal life in heaven with Him some day?

These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage. Jude v:16

It's so easy to get caught up in complaining. I've done it myself more times than I'd like to admit. The thing is, when we complain, it could sound to Jesus like we are ungrateful for all He's gone through and done for us. He gave up the easy life in heaven and came down and became man to suffer the same things other humans do. This perfect Son of God, was betrayed by his so-called friend, Judas, was mocked, spit upon, was crucified and was buried. 

Fortunately for us, He is the Son of God and He arose the third day to save us from all our sins, if we believe in Him. It seems like one of many of these sins is complaining that we don't have more and be ungrateful for all He's already given us.
