To finish is to end, complete, accomplish, or bring something to its appointed conclusion. Depending on context, the word may be rendered complete, accomplish, fulfill, end, or bring to completion. It can also describe something becoming full-grown rather than merely being completed.
Scripture uses finish for completing a work, accomplishing a purpose, ending an activity, and fulfilling what has been appointed. Its most prominent biblical use is Jesus’ declaration “It is finished” on the cross, expressing the completion of the work being described in that passage.
