When Jesus came near the end of His life on earth He could say to His Father that He had completed the work He was sent to accomplish. Remember two passages that clearly say why the Father sent His Son into the world that first Christmas.
1 Timothy 2:15 - "...Christ Jesus came into the world to save sinners..."
1 John 4:14 - "The Father sent the Son to be the Savior of the world."
Of course, this was also seen in why His name was Jesus: Matthew 1:21, "...you shall call His name Jesus, for He will save His people from their sins.
But are we aware that the gathering of souls into the Kingdom is still ongoing? Though Jesus accomplished all that was necessary to save sinners, the work of getting this messge out to the world is now our responsibility. We, too, have a work to do for the Lord. Some believers may be ashamed at the end of their lives not that they didn't finish what God called them to do, but that they never really got started.
I've been urging folks to look around them where they live, work, and study. You're there for a reason. And much of that is to make the Gospel clear to those you live with, work with, or study with. You make it clear not only by what you say, but by how you live. Are you seeking to "finish" what God has called you to do?
