There are seven parables spoken by the Lord in Matthew chapter 13 only three of which are also mentioned in Mark and Luke and none in the gospel of John.
While the gospels record about thirty parables mentioned by Jesus; these seven are significant because they reveal the mysteries of the kingdom of heaven, or as Jesus called them in Mark 4:11, “the mystery of the kingdom of God”.
“I thank God, whom I serve with a pure conscience, as my forefathers did, as without ceasing I remember you in my prayers night and day, greatly desiring to see you, being mindful of your tears, that I may be filled with joy, when I call to remembrance the genuine faith that is in you, which dwelt first in your grandmother Lois and your mother Eunice, and I am persuaded is in you also.” 2 Timothy 1:3-5.
“The Lord is my shepherd; I shall not want. He makes me to lie down in green pastures; He leads me beside the still waters. He restores my soul; He leads me in the paths of righteousness for His name’s sake.” Psalm 23:1-3.
“I waited patiently for the Lord; and He inclined to me, and heard my cry. He also brought me up out of a horrible pit, out of the miry clay, and set my feet upon a rock, and established my steps.” Psalm 40:1-2.
