A garden might be a good representation of the spiritual lives of Christians. The ‘birds’ and ‘animals’, spiritually speaking, are all those worldly things and worldly people we encounter every day, that mess us up with their bad influences. The ‘plants growing wildly’ represent our spiritual activities, which need to be trained, nurtured and pruned so that they go God’s way. The ‘weeds’ represent the sin in our lives which threatens to take over if we are not careful. Much work needs to be done if the Christian’s spiritual life is not to become chaotic.
