Believers are commanded to “Be careful for nothing.” Contextually, the word careful means to be care full or full of cares. That being said, this is one of the most disobeyed commands in all of scripture. In Matthew 6:25, the Lord warned His disciples against dwelling upon or worrying about what they would eat, or drink, or how they would be clothed. The Lord’s rebuke implies that not even the necessities of life should serve as a source of worry for God’s people. It is important to note that worry and faith are at opposite ends of the spectrum because they do not and cannot coexist within the believer’s life and walk. A believer who is “careful” for things cannot and will not simultaneously trust God’s faithful provision. When a believer worries rather than trusting in God’s provision and protection, the believer’s actions deem God incapable to accomplish the matter without the individual contributing his “carefulness.”
The Lord wants His children to have joy and that without limitations. He wants Christians to experience the fulness of joy that only comes from right relationships. This fulness only exists in the lives of believers as certain conditions are met. The right relationship involves fellowship with God which in turn evolves into the right kind of fellowship with other believers. According to today's passage, the words of the Lord Jesus bring fulness of joy to the saint of God. Additionally, answered prayer offers fulness of joy (John 16:24). In addition to our fellowship with the Lord, the Bible suggests that fellowship with other believers also yields fulness of joy (2 John 1:12). Every astute Bible student recognizes that these two fellowships are inextricably linked (1 John 1:3). No dedicated Christian can experience true fellowship with other dedicated believers without first having the right kind of fellowship with God Almighty.
