Guernsey FC manager Tony Vance says survival is in their hands after seeing his side draw 1-1 with relegation rivals Greenwich Borough at Footes Lane.
The result leaves the two teams level on 29 points at the bottom of the Bostik South East, with the Green Lions one spot above safety.
It looks likely that one of the two will go down, although Guernsey have a game in hand and a superior goal difference.
Dave Rihoy gave GFC a first-half lead in Sunday's crucial clash, before the visitors levelled from the spot soon after the break.
Guernsey had a golden chance to seal all three points, but Will Fazakerley saw his late penalty saved.
Vance's men play twice on Easter weekend - away at mid-table Phoenix Sports and home against play-off chasers Horsham, before finishing their campaign at 16th-placed Sittingbourne.
Greenwich Borough's Tony Robinson was taken from the pitch in an ambulance after landing nastily on his back, but Guernsey FC confirmed he was able to travel back from the island following a check-up.
