We know God's grace is effectual through the transformative power it has in the hearts of believers.
The effectual calling is evidenced in the believer's life through a profound change of heart and affection towards God. 1 Thessalonians 2:13 states, 'For this cause also thank we God without ceasing, because, when you received the word of God, which you heard of us, you received it not as the word of men, but as it is in truth, the word of God, which effectually worketh in you that believe.' This passage confirms that God's Word, when received as truth, works effectually in the hearts of those He has called. Genuine transformation, a desire for holiness, and a true affinity for Christ arise from this effectual call, showing us that God's grace indeed has a powerful, non-resistible impact.
