The seed falling on rocky ground refers to someone who hears the word and at once receives it with joy. (Matthew 13v20 NIV)
Everyone receives their salvation with joy.
It is is a sudden event.
It can even be a surprise to you and others.
It is as if you have discovered something unexpected.
A whole wonderful world opens up inside of you.
Your spirit comes alive and you experience something which is brand new.
Everything seems different.
There is now light where there was darkness.
Hope where there was hopelessness.
That event was wonderful.
But there is more.
Much more, that was just the start.
