1 Cor 15:10 But by the grace (the unmerited favor and blessing) of God I am what I am, and His grace toward me was not [found to be] for nothing (fruitless and without effect). In fact, I worked harder than all of them [the apostles], though it was not really I, but the grace (the unmerited favor and blessing) of God which was with me.[AMP]
Paul makes this statement with full revelation that he was in a blessed position because of the Grace of God. We must never take for granted that Grace is just a free get out of jail card. In 1 Corinthians 1:4-6 Paul speaks of blessing using these key words; favor, spiritual blessings, enriched, readiness of speech. The last part of the scripture ends with these words “complete knowledge and in our witnessing concerning Christ was so and established and made sure in you”.
We know that Grace is God unmerited favor, however as the words written in 1 Corinthians 1:4-6, provides us with a view of our responsibility because of Grace we should understand we have divine responsibility to display the principles of obedience and faith. In life,words and actions must be consistent with our faith. This is the aspect in which Grace is most effective is when we fall short in our ability the unmerited favor of God is designed to help us complete his divine will in us.
So today know that God has equipped us to do His will. His Grace is his unmerited gift to us not based on what we have done but designed to facilitate what we do in him. As Paul stated; by the Grace of God I am what I am, and his grace toward me was not for nothing. Just as Paul we must have the determination to work harder in the principles of the kingdom as part of our display of faith and what we believe in God.
