The kingdom of God is … righteousness and peace and joy in the Holy Spirit.
If you’re a Christian and you don’t have joy, here are some very basic things you need to understand about what it means to have the joy of the Lord in your life.
Receiving Christ, submitting to the Spirit, reading the Bible, and praying doesn’t sound very original. But there isn’t anything more original than the Word of God. That’s the bedrock simplicity of what it means to have joy in Christ. Here is why: If joy is in Christ, then everything that has to do with joy has to be centered on Christ.
As the Holy Spirit indwells and controls us, and as we read the Bible, we will come to prayer time and into fellowship with Jesus. As we spend time with Him, we come to love, adore, and praise Him, and Jesus becomes literally the focus of our lives. That is how we have joy in God.
Christian joy isn’t always laughing, always having a good, hilarious time. Christian joy is the deep, settled peace that comes to live within your heart when you know that the really important things are all right. Life can be taken from us, but we are going to live somewhere for eternity. You can have joy in your heart when you know everything is all right with you forever.
