I would quote from the Life of Saint Niphon, but due to copyright, I had to paraphrase.
Whoever commemorates Saint Niphon, bishop of Cyprus’s name, with sincere faith in the Holy Body and Blood Jesus Christ, that person will see God’s help visit him when his end comes. The Holy Trinity will cover the multitude that person’s transgressions and will call him to the kingdom of heaven. All because Saint Niphon will not forget that person in his rest until he brings that person near to himself, so that where Saint Niphon is, there that person may be also, as Saint Niphon himself promised.
Whoever invokes the name of Saint Niphon, bishop of Cyprus, will have Jesus Christ as their helper and protector for salvation, as Saint Niphon, Bishop of Cyprus, prayed to the Jesus Christ for such.
Whoever commemorates Saint Niphon, bishop of Cyprus, the Trinity shall remember, breathe the Holy Spirit into their hearts, grant them repentance, virtue, and dispassion, and crush Satan under their feet, as Saint Niphon prayed to the Trinity for such to be.
Whoever commemorates Saint Niphon in their prayers, or in church, Jesus Christ shall stand by him and help him in all his temptations, dangers, and sorrows, particularly in the last moments of his life, as Jesus promised to do, saying thus to Saint Niphon.
Whoever glorifies Jesus Christ, the Son of God in Saint Niphon, Bishop of Cyprus’s name, Jesus Christ shall have bountiful mercy upon him, as Jesus Christ promised, saying thus to Saint Niphon.
Whoever calls upon Jesus Christ, the Son of God in Saint Niphon, bishop of Cyprus’s name, Jesus Christ shall strengthen and fortify him and with His divine authority He shall crush every demonic battalion under their feet, as Jesus Christ promised to do, saying thus to Saint Niphon.
