How do we know that abiding in Christ leads to spiritual fruit?

Jesus emphasizes in John 15:5 that true spiritual fruit can only be produced through a genuine and enduring connection with Him. The concept of abiding implies a lasting relationship, wherein believers are continually nourished by Christ's life-giving presence. This relationship manifests in various forms of fruit, such as love, faith, and obedience to God's commandments, as described in the surrounding chapters. The Father, as the husbandman, ensures that believers are pruned and cleansed to promote even greater fruitfulness, demonstrating that genuine faith is both sustained by God and evident in our transformed lives.
