“We are invited to bless the Lord; we are commanded to bless the Lord. And then someone says, “But I don’t feel like it. And I won’t be a hypocrite. I can’t bless God if I don’t feel like blessing God. It wouldn’t be honest.” The biblical response to that is “Lift up your praising hands to the Holy Place, and bless GOD!” You can lift up your hands regardless of how you feel; it is a simple motor movement. You may not be able to command your heart, but you can command your arms. Lift your arms in blessing; just maybe your heart will get the message and be lifted up also in praise.”
