It's important that things be kept simple as to not overwhelm new believers.
And, all new believers should be aware that the enemy will do his best to choke God promises out of them in an attempt to get them to give up on being a Christian:
Mark 4:13-20
And he said unto them, Know ye not this parable? and how then will ye know all parables?
The sower soweth the word.
And these are they by the way side, where the word is sown; but when they have heard, Satan cometh immediately, and taketh away the word that was sown in their hearts.
And these are they likewise which are sown on stony ground; who, when they have heard the word, immediately receive it with gladness;
And have no root in themselves, and so endure but for a time: afterward, when affliction or persecution ariseth for the word's sake, immediately they are offended.
And these are they which are sown among thorns; such as hear the word,
And the cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word, and it becometh unfruitful.
And these are they which are sown on good ground; such as hear the word, and receive it, and bring forth fruit, some thirtyfold, some sixty, and some an hundred.
These are the 5 things satan uses to choke God's promises out of a person's like if these things are allowed to enter in to their life... all Christians should know this cause Jesus just explained satan's game plan here.
1 Peter 5:8,9
Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
Whom resist stedfast in the faith
