“If you then, who are evil …”
The Lord Jesus used the phrase “your Father” a full eleven times in the Sermon on the Mount in Matthew 5 through 7, including in this very verse. In full, it reads, “If you then, who are evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask him!” He was primarily addressing those who believed in him, trusted in him, and were seeking to follow him. (Throughout scripture, God is never “your Father” to the unbelieving world — I have yet to discover a single instance — though he certainly created it and seeks to call its lost to himself.)
