God plainly states that He can rejoice, and His rejoicing is not limited to times of happiness or exuberance. He rejoices in both blessing and cursing, finding satisfaction in doing what is right, even when it involves painful judgments upon the guilty. His rejoicing encompasses a knowing satisfaction that His actions, whether in blessing or judgment, are just and purposeful. God does not confine His rejoicing to moments of joy, as He finds fulfillment in the correction and guidance of His people, even when it brings pain to effect change. His command for us to rejoice during His feasts reflects this broader understanding, urging us to brighten up with anticipation of His purposes, recognizing that there is always a point and purpose in everything He does. God's rejoicing, even in judgment, serves as a model, showing that satisfaction comes from aligning with His will, whether in times of prosperity or trial. He desires for us to rejoice in the context of His feasts, not as a mere celebration, but as a reflection of His deeper intent, connecting our attitudes and actions to His overarching plan.
