When we first come to Christ we might think “What a bummer. I can’t do what I want.” But then you begin to live for Him and you realize that this new life you’ve been given is better then what you could’ve imagined. You have “life more abundantly”.
It’s the same way on a smaller scale too.
If He is asking you to give something up He’s going to replace it with something far better.
Keep this in mind and the growing process will be a lot easier.
