The joy of life is God's will for you. That doesn't mean that you will have no problems. It does mean that the presence of God will give you strength through joy. The psalmist said to God, "In Your presence is fullness of joy" (Psalm 16:11). That's the presence of God in believers through the Holy Spirit. The fruit of the Spirit includes fullness of joy.
The joy of life is not dependent on outward circumstances or other people. True joy comes from within. It is dependent upon your relationship with God. Even in difficult circumstances, you can be filled with the joy of the Lord. He is the joy of life.
Restoring the joy of life comes through confessing our sins to God, that the joy we once knew may be restored. Sin separates us from fellowship with God. Restored fellowship brings fullness of joy. The barrier of sin is removed as we turn away from sin and confess it to God. The joy of life is restored. We pray,"Restore to me the joy of Your salvation"(Psalm 51:12).
Genuine worship is from the heart. It refreshes us with the presence of God's joy. In His presence there is the joy of life. His joy is our strength for living. Worship makes us aware of God's presence. His presence is the place of joy. Restore your joy now in God's presence. He is the joy of life.
