We love to picture Jesus pressing forward, fingers punctured with slivers, hands wrestling with His cross, legs wobbling, now bending, stumbling, stooping, picking Himself up - we see Him force Himself to the site of His execution, His execution for us.
But did not Jesus also do what He did for someone else, namely for His Father? Was not Jesus motivated to fulfill His mission because He also sought to win for His Father the glory of salvation? An because Jesus came to work the will of His Father (John 4:34), can we not say that Jesus was motivated to fulfill His mission, despite the opposition He faced, because He enjoyed His Father's authorization?
