Luke 11:13

If ye then, being evil, know how to give good gifts unto your children, how much more shall your heavenly Father give the Holy Spirit to them that ask him?

Here the contrast between evil men and the righteous Father is stressed; there is also a contrast between the "good gifts" of earthly fathers (such as food) which are surpassed by the greatest of gifts, that of the Holy Spirit, the gift which includes all others. In the similar record of Matthew 7:11, the Saviour represented the Father as giving "good gifts," as distinguished from "the Holy Spirit" here. This emphasizes the difference in the two occasions. As Childers noted:

This discourse in Luke comes later in Jesus' ministry and nearer to Pentecost than does the Sermon on the Mount, in which the passage cited in Matthew occurs. Therefore, Jesus can be more specific with reference to the needs of his disciples.[19]

From the passage here, it is clear that God's children should not hesitate to pray to the Father for the measure of the Holy Spirit which has been promised to baptized believers (Acts 2:38), and which is called "an earnest" of our inheritance (Ephesians 1:13).
