As the sovereign Creator and Lord of everything, our heavenly Father rewards those who fear him and not those who fear the opinions and approval of other people (6:1). In a world that is ravaged by fear of man and gaining the approval of others, God wants us to see him as the most supreme and valuable being to fear. Not because he is narcissistic and out of control, but because what our hearts desire (approval and acceptance) can only be truly found in fearing God. Fearing anything other than God will only lead to disappointment and despair. Fear God is the beginning of wisdom and the ultimate experience of true joy.
Only a Father who is separate, different and set apart from this earth (only a Father who is heavenly), can accomplish all this in and through us.
