And Jesus called a little child unto him, and set him in the midst of them,
And said, Verily I say unto you,
Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.
Whosoever therefore shall humble himself as this little child,
the same is greatest in the kingdom of heaven. Matthew 18:2-4
That scripture tells us we must be humble.
So, where do you get faith in the first place?
For I say, through the grace given unto me, to every man that is among you,
not to think of himself more highly than he ought to think; but to think soberly,
according as God hath dealt to every man the measure of faith. Romans 12:3
God has given to every man faith.
We decide what to do with that faith we have been given.
Some squelch it or refuse it or think of it as rubbish.
Some follow after it and do whatever it takes to get more.
Just like the seeds that are spread on the different ground, we allow it to grow in our hearts, or not.
Now the parable is this: The seed is the word of God.
Those by the way side are they that hear; then cometh the devil,
and taketh away the word out of their hearts, lest they should believe and be saved.
They on the rock are they, which, when they hear, receive the word with joy; and these have no root, which for a while believe, and in time of temptation fall away.
And that which fell among thorns are they, which, when they have heard, go forth,
and are choked with cares and riches and pleasures of this life, and bring no fruit to perfection.
But that on the good ground are they, which in an honest and good heart, having heard the word, keep it, and bring forth fruit with patience. Luke 8:11-15
So, the seed is the word of God.
And this scripture fits in nicely right here:
So then faith cometh by hearing, and hearing by the word of God. Romans 10:17
Quite simple. Our part is to be humble before the word of God.
To hear the word of God which means if we want our faith to grow,
we must be actively participating by reading it, applying it in our lives and accepting it.
