Simply put, the only way to see or enter into the kingdom of God is by a marvelous and irresistible act of grace performed on a person by the sovereign work of the Holy Spirit.
When we see ourselves as we truly are, we see the need for a sovereign Savior. When we see that we are helpless without Him, we take great comfort in learning that Jesus did it all for us by the GRACE of God.
Salvation is complete in Jesus Christ. Therefore, when Jesus was born into the world, God’s salvation of His people was as good as done! No matter what man would try to do, God was saving His people.
