For Jews request a , and Greeks seek after wisdom; but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. 1 Corinthians 1:22-24 New King James Version
The reason people do not understand the Gospel message it two fold. It is not just their minds but their hearts as well.
With the Jews they were all about religious rites that earned Gods grace so the message of the cross was insanity to them.
To the Greeks everything had to have a logical reason behind it. Christs sacrifice was illogical so it was foolishness to them.
It is the same today If peoples hearts and minds are not open to receive the message it will be insanity and foolishness to them.
Prayer: Please Jehovah Shalom (God of peace) bless me with the peace to know I have tried to share Your message and it was rejected. It hurts when those I love mock me and persecute me because I am Your child It frustrates me when they refuse to accept Your divine message. I humbly request this in the name of He who was initially mocked and rejected by His earthly family Jesus Christ. Amen.
May the sunshine of Jesus’ sweet love bless you today and every day
