“The natural man does not receive the things of the Spirit of God for they are foolishness to him; neither can he understand them for they are spiritually appraised” (I Corinthians 2:14).
“Are you getting this?”
“Am I getting through to you?”
Ask any teacher. Trying to convey a lesson to the clueless is the toughest part of their job. The students sit there and stare at you as though you are speaking Swahili. They just don’t get it.
Matthew 16 has three groups that do not get what the Lord Jesus is doing and teaching.
The Pharisees and Sadducees (16:1-4). They wanted a sign. The Pharisees were the ultra-conservatives of that day and the Sadducees the ultra-liberals. The only thing they had in common was an animosity to Jesus.
These so-called religions authorities had no time or energy to consider what Jesus was doing and saying and what it meant. By asking for a sign, they were saying: “If you want us, you’ll have to overwhelm us with your miracles so we have no choice but to believe.” But without faith, it’s impossible to please God (Hebrews 11:6) and the just shall live by faith (Habakkuk 2:4; quoted in Romans 1:17, Colossians 3:11, Hebrews 10:38).
No one enters the Kingdom who is unwilling to come by faith in Jesus Christ.
