When God removes an infirmity or gives a blessing, He also gives a responsibility to follow through, using the blessing to overcome and glorify God.
The storm on the Sea of Galilee instructs us that when we are in a trial and getting nowhere, if we invite Christ into the situation, we will have peace.
Christ's miracle of feeding the 5,000 is the only miracle that all four gospels record. Jesus used the circumstances to teach His disciples lessons for after His death.
The feeding of the 5,000 tells us far more than that Jesus was a miracle-worker. It also reveals Christ's compassion on those who hunger, plus His ability to teach.
All of us who are called by God are so precious in His sight that Jesus Christ, before we were even born, died for us, saving us from oblivion.
