A friend of mine several years ago wanted to lose weight. One January she bought a treadmill. The postal worker told her before it arrived, "So you got a new clothes hanger?"
And he was right because he'd delivered lots of exercise equipment to people who used it for a time but then gave up. Why did they give up? Maybe they gave up because the results weren't fast enough or because it involved a lot of work. I'm guessing both of these reasons.
I'm no different. I haven't invested in exercise equipment but I've put myself on specific eating plans and decided to do some kind of exercise so many times per week. And most of the time all that lasts about two weeks (if that and the diet plans never work for me -- NEVER).
No matter what equipment we have, no matter how much we outfit ourselves with the latest and greatest, reaching goals takes time and work. There are no magic buttons. God could have provided us with magic buttons but he didn't. The process of growth is the way He works in us. That process is absolutely necessary for us to become who we were created to become.
The process of living a Christian life is similar. So many of us accept Christ and maybe read our Bibles but then fumble through life wondering why it didn't change when we accepted Christ.
Life isn't going to change. It will be full of ups and downs; lack and luxury; harvest and planting.
For us to live a full-of-life Christian life we must apply ourselves. We must do the work. If we want spiritual growth we need to start believing God and His word even when it appears impossible (especially when it's impossible for God is the God of impossible things).
Reading the Bible is good and a great place to start and it is absolutely necessary to the next part -- that part being applying that word. It isn't easy to do. It isn't easy to let that Word soak into us and live by it when our bodies and our minds and emotions are telling us it won't work. We have to be reprogrammed. And that takes time.
"And (Jesus) didn't do many miracles there because of their unbelief." Matthew 13:58
"And the one on whom seed was sown on the good soil, this is the man who heard the word and understands it; who indeed bears fruit, and brings forth some hundredfold, some sixty, and some thirty." Matthew 13:23
That guy above asked God for understanding cause we can't understand spiritual truths without God's help. Once he understood he allowed it into his person fully, and his life bore fruit.
We can't bear spiritual fruit if we don't let the Word transform us.
(A few things that hinder this process:
Fear, worry, lust, love of money, bitterness.)
You can do it! I know you can. Jesus came to give us abundant life, not a measly puny life.
