The apostles of the early church had a great assignment. Their assignment required the grace of God. The grace of God is described as God's willingness to make His power and ability available for the benefit and favor of His children. As a result of the grace of God the early church grew in influence and size - Acts 4:33 & 2:47.
Similarly it will take the grace of God for you to accomplish your God-given assignment. Apostle Paul acknowledged the divine favor of God in his ability to fulfill destiny - 1 Cor 15:10. Whatever God has called you to do will take more than just your natural abilities and labor. God wants to make His power available for your success; His desire is for you to labor by grace.
As you labor factor in the grace of God. The grace of God is a difference maker. By the grace of God your natural efforts are supernaturally magnified, and your results are supernaturally amplified.
