We know we are of the Spirit by producing the fruits of the Spirit, such as a contrite heart and a reliance on Christ.
To ascertain whether one is truly of the Spirit, Winslow emphasizes the importance of evidence manifested through the fruits of the Spirit. A brokenness over sin, a conviction of unworthiness, and a simple faith in Jesus are authentic indicators of a renewed heart. This means that genuine spiritual transformation leads to a life marked by humility, a desire for holiness, and a reliance on God's grace rather than human efforts.
Moreover, the assurance of being in the Spirit should not lead to complacency. Believers are encouraged to continuously strive for spiritual growth and conformity to Christ. It's not enough to merely identify as regenerate; one should engage in a lifelong pursuit of walking in the Spirit, which involves sowing to spiritual matters and being content with the Lord's direction in life.
