S – The Pharisees came and began to argue with him, demanding of him a sign from heaven to test him. ¹² Sighing deeply in his spirit, he said, “Why does this generation demand a sign? Truly I tell you, no sign will be given to this generation.” ¹³ Then he left them, got back into the boat, and went to the other side.

Mark 8:11–13 CSB

O – Commentary: 

What they sought was a miraculous sign from heaven—that is, directly from God—that would demonstrate once for all that Jesus was the Christ. No sign, however, could ever convince them of this. For those whose hearts were open to the truth, the miracles that Jesus had already done (Luke 7:22) were clear and irrefutable signs that Jesus was the Messiah, the Son of God. For those outside (4:11–12), no sign could make them believe (cp. Luke 6:19–31).

 New Living Translation Study Bible 

A – It comes down to the heart.  If your heart is open to God and His Truth, a sign would affirm what you believe.  If your heart was closed, a sign would confirm. Promova: “Affirm’ often implies making a statement or assertion to validate or declare something as true.  ‘Confirm’ generally implies verifying or establishing the truth or accuracy of something, often as a subsequent or additional assurance.”  I want to declare who God and Christ is, not test Him.

R – Heavenly Father, I ask for your Holy Spirit to lead me in all truth today.  I affirm that You are God and there is no other.  I affirm that Jesus is the Son of God and my savior.  Help me to model the love You have for me to others today in my thoughts, words and actions.
