When the beloved James told happy saints to sing, James 5.13, perhaps he instructed them to do this because that is what God does.
The Lord your God is in your midst, a mighty one who will save; he will rejoice over you with gladness; he will quiet you by his love; he will exult over you with loud singing.
Zephaniah 3.17 ESV
God loves to save people. It makes him happy. He and all the heavenly host rejoice when someone repents, Luke 15. He breaks out in song.
Excuse my manner of speaking, but you and I can make God sing.
God saves today through his people proclaiming the Good News. When we fail to do it, there is no salvation for others. He has put his church on earth as his mission agent to save others. What an amazing thought!
Unfortunately, few of his people today cause God to sing. Many have left up sharing the gospel to others, especially to people paid to do it.
Not only does God not sing at that, he is deeply saddened. He mourns. He sees so many weighed down by self-interest, busy schedules, worldliness, entertainment, insecurity and doubt. They fill their lives with things that will perish. They fail to find the certainty of truth. They let Satan obscure their vision of God’s greatness and goodness. They leave off Scripture and prayer.
Before we can help others, Jude 22-24, we must follow Jude’s instructions:
But you, dear friends, by building yourselves up in your most holy faith, by praying in the Holy Spirit, maintain yourselves in the love of God, while anticipating the mercy of our Lord Jesus Christ that brings eternal life.
Jude 20-21 NET
Both Jude and James end their letters with the need to save others, just as Jesus ended his ministry by giving his people the mission of proclaiming salvation, Matthew 28.18-20. Peter sets his imperative smack dab in the middle of his first letter:
But set Christ apart as Lord in your hearts and always be ready to give an answer to anyone who asks about the hope you possess.
1 Peter 3.15
Peter ties together making Christ the Lord in our hearts and readiness to explain our hope. If we are not doing the latter, we have failed to do the former.
How do we hope to enter into the joy of our Master eternally, when we fail to give him joy now?
The joy of salvation is not only in having it, but in sharing it as well.
Make God sing for joy. Show someone how to be saved.
