To fully benefit from having God as my Father, I must admit that I need him as provider, protector, counselor, guide, comforter and savior. I must admit "I can't," acknowledge "He can," and believe "He will." Only then can I know the full value of having been adopted into his family and having the privilege of calling him "Abba Daddy."
John 5:1-18 tells the story of a crippled man. When Jesus asked him "Do you want to get well" he replied that he had no one to help him get into the healing pool. He knew of only one way to get healed. Sometimes I limit God the same way. I say "Lord, I can't be happy unless ____." Then I get discouraged and disgruntled if my specific request is not granted. I need to be willing to say "Lord, do whatever you think is best in my life and I'll be happy no matter what you provide."
Should I view Jehovah as a god of joy (and praise him) or a god of responsibility (and serve him?) Of course the answer is "both," since worship is defined as "recognizing and properly responding to God." Service is part of that proper response. Too much emphasis on the joy part can cause a turn inward, always looking for the next bit of spiritual excitement. Too much emphasis on the responsibility portion can result in guilt and lifeless attempts to minister. Our challenge is to find and retain the joy that comes from fulfilling responsibilities.
