2 Chronicles 7:14
“if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land.
The word picture behind "seek My face" is: "the beginning action to work a slow twisting".
This is like an encounter between an unruly branch on a grapevine and the vinedresser.
Vine branches have a mind of their own. Hence, their capacity to fulfill their purpose (producing much fruit) is dependant on a face to face encounter with the vinedresser.
Sometimes it is a real wrestling match to get the branches growing around and over the support structure built by the vinedresser. At times the branches have to be pruned to get them growing around the supports.
John 15:1 & 2 “I am the true vine, and My Father is the vinedresser. “Every branch in Me that does not bear fruit He takes away; and every branch that bears fruit He prunes, that it may bear more fruit.
To "seek His face" is to submit to His handiwork in our lives as the Vinedresser.
