John 10:10 (NKJV)
There are things people do because they have to do them, but there are other things people do that they like to do and they look forward to doing them. Many people have a job they dislike but look forward to their weekends and vacation because that is when they can do what they like and have fun. Some people are fortunate enough to have a job that they enjoy but even then there are often aspects of that job they are not happy with. It usually seems as though our work and the things we enjoy do not go together and most of the time we have to choose between one or the other.
Often Christians have difficulties because ideas and concepts from the world get into their thinking. Many Christians either completely believe, or they at least accept the idea, that we can either serve God and do His will or we can have a wonderful life. For many Christians the idea the Jesus came to give us an abundant life is something that they only consider for their personal well-being and it is not usually seen as having anything to do with the Church or serving God. Too often people, including Christians, think that Christians have to choose between bearing fruit for God or having fun in life; the good news is that we can have both.
When Jesus talked about people having an abundant life He was talking about a life lived fulfilling the will of God. Too many people try to live a life fulfilling their own wishes and desires, not realizing that by following God's plan for their life they would not only be in line with the purpose that God created them for but that as they follow God all of their personal goals would also be fulfilled (Matthew 6:33). God created us for a purpose (Ephesians 2:10), He has given us a gift to use for His glory (1 Peter 4:10), and His plans for us are always good (Jeremiah 29:11). Living a godly life should include both fruit and fun.
