Yahweh turned the captivity of Job, when he prayed for his friends. Yahweh gave Job twice as much as he had before - Job 42:10
God doesn't live on the flip side of greatness. That's why everything written about Him is great. More so, the Lord God delights in your greatness. That's why the scripture says that a little one shall become a thousand (Isaiah 60:22). So, when God enlarges a man, it means NO MORE LIMITATION. The lifestyle of Jabez didn't match up to God's plan for his life until he prayed that God should bless him indeed and large his territory. If you would pray and pin your faith on God's word, your life would begin to experience enlargement in Jesus name.
When God enlarges a man, for such one, it means NO MORE LIVING IN OBSCURITY. David was living from one cave to the other running away from the harm King Saul could inflict on him. But when God enlarged his coast, he became king over Israel and reigned in dominion. God's touch relocated him out of obscurity into the spotlight. If you think God has forgotten you, Job shared the same thinking, but was later enlarged such that his latter was greater than his former.
Finally, a divine visitation to enlarge your coast means NO MORE LIVING AT THE MERCY OF TORMENTORS. When God makes you a spiritual giant, demons molesting you keep off because they know that you aren't a weakling they can trample under feet. Because the Lord God enlarged David, by reason of the anointing upon him, he was able to confront Goliath, the tormentor of the children of Israel, and brought him down to defeat. As the Lord enlarges you, may you begin to shine, occupy God's provisions for your life and become stronger and mightier to do exploits in Jesus name.
