Mark 8:21 He said to them, “Do you still not understand?”
Jesus used many parables and similes when He talked about the Kingdom of God; doing so to try and allow people to understand His ways.
But if someone does not want to hear the truth, thinking they know it all, they will not understand what you say – because they are not listening!
If you want someone to know about Christ, don’t talk at them, talk with them and share your love for Christ.
