Jamieson, Fausset and Brown on Matthew 7:11

11. If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him!--Bad as our fallen nature is, the father in us is not extinguished. What a heart, then, must the Father of all fathers have towards His pleading children! In the corresponding passage in Luke (see on Lu 11:13), instead of "good things," our Lord asks whether He will not much more give the Holy Spirit to them that ask Him. At this early stage of His ministry, and before such an audience, He seems to avoid such sharp doctrinal teaching as was more accordant with His plan at the riper stage indicated in Luke, and in addressing His own disciples exclusively.
