Psalm 92:13-14 Those that be planted in the house of the Lord shall flourish in the courts of our God. They shall bring forth fruit in old age: they shall be fat and flourishing.
Through faith in the Gospel, the Holy Spirit plants us in the house of the Lord, that is, the Spirit enters our bodies and dwells there with His Presence. The body houses the Spirit of God which causes us to flourish and bring forth fruit. Flourishing is the believer’s response to the indwelling Spirit.
The fruit of the Spirit (love, joy, peace, etc,) is worked in by the Spirit and then worked out in our lives. The pleasant outcome is a fruitful flourishing of God’s beautiful life in us and through us. This comes about through faith in the gospel which plants us firmly in Him. We abide in Christ and so bear much fruit. Christ is the vine and we are the branches. We plant ourselves in Him by hearing the Word weekly and daily.
