Easy steps to an abundant life?

I won't doubt it that a lot of Christians are wondering where the promised abundant life is after they became Christians. It seems that they are all doing the right thing, reading their Bibles, saying prayers, even doing the "work of God". But somehow, they do not feel right inside their hearts, sometimes, even while sitting in a church, they feel there must be something more than what I'm currently experiencing.
In bookshops, they sell books like, 5 steps to a debt free life; or 6 steps to long term weight loss; but I don't really think the same formula applies to Christian life.
Because there have been lots of Christians attended such seminars, read such books, but no, they have not found the abundant life yet.
Shouldn't it be natural that as soon as we know the Messiah, we accept Him as our Savior, we would just start to experience the abundant life He promised naturally?
But real life experience doesn't seem to confirm it.
Why?
I think, the vital point is, is the Christ we think we know the same as the true Christ? Are the characters we perceive that He has truly His?
We can run all the campaigns and seminars giving a list of things to do and to avoid to become successful Christians, but if the picture of God is not right, it will only still remain a religion centered around us.
If we ask Christians today, how did humanity first fall? I think most of them would answer, because our ancestors ate a piece of forbidden fruit.
But look closely, we know that before someone does something, he needs to have a motive.
What was their motive of eating that fruit?
You may say, because they had jealousy and pride, and they wanted to become like God.
But pause a second, where did they get this idea that when they eat the fruit, they would become just like God?
Did Yahweh say that? No, God only told them the reason He did not allow them to eat the fruit was to prevent them from death. It was the devil who made up this lie, deceiving them to believe if they eat the fruit, they would become as wise as God.
What the devil was saying was, God told you if you eat the fruit, you'll die, but let me tell you the truth, you won't die, but you will become like God. God lied to you, the reason He doesn't want you to eat the fruit is because He doesn't want you to become like Him, because then, His supremacy will be threatened, He doesn't want the competition, He wants to be above everyone else; so the only excuse He could make up to prevent you from eating the fruit is telling you you will die. So, look at God again with me, He is selfish, jealous, and a liar! Don't believe in Him, believe me!
And so, Eve believed it.
Don't say we human race fell by eating a piece of fruit, because then we would be focusing on our deeds which lie on the surface; but I believe the root needs to be addressed; and the root of our rebellion is a wrong, twisted picture of God. We don't see Him as who He is, then it becomes inevitable for us to rebel against Him.
