Luke 8:9-10 His disciples asked him what this parable meant. 10 He said, “The knowledge of the secrets of the kingdom of God has been given to you, but to others I speak in parables, so that,
“‘though seeing, they may not see;
though hearing, they may not understand."
When Luke talks about the secrets of the "kingdom of God" today, it is in the context of the parable of the sower. Parables use earthly analogies to give a spiritual lesson. In this case Jesus used an illustration from farming to show when the Word of God is planted in the right soil it will produce an exponential yield. Jesus realizes that some people will want to find the ultimate meaning and truth from this story, and some will never dig any deeper than the surface.
Though the story of the parable of the sower is true in farming, it is also true in God's kingdom. God's kingdom is where he is ruling or reigning. Jesus says the secrets to it have been given to the disciples, but others may see about it or hear about it, but do not understand. So this brings up the question of why some see these secrets and some don't? Why do two people hear the same story and one completely misses the point and one gets it?
The first question might be does God want to hide these secrets from some, and yet reveal it to others? Secondly does the secrets of the kingdom get realized by those who want to seek and find the kingdom? This is spoken of in the Bible when it says, "those who seek will find". In another parable in Matthew's gospel, we see the person who gave up all they had to find the pearl of great price. So we see a tension here.
Later as the disciples began their ministry, the only way they could see if the secrets worked was to apply its principles. In this story they had to realize that if they sowed the seed liberally that some of the seed would fall on good soil and others on soil not receptive to it. Although they did not know which soil would be receptive or non-receptive, they had to trust this secret of kingdom that if they sowed liberally God would make some of it grow.
So are they secrets, or an invitation to be part of God's kingdom coming here on earth as it is in heaven? Just like one might say the "secrets of being a good salesman". The only way to find out if a secret like this is true you have to apply its principle and see the results. God invites you and I to be a part of His kingdom growing and He has given us His Word to spread to as many people as we can. Some will fall on bad soil and some on good soil, but today's secret is that if we are faithful God will make it grow some 30,60 or 100 times. Let's go find out if the secret is true.
