Westminster Larger Catechism

Q79

May not true believers, by reason of their imperfections, and the many temptations and sins they are overtaken with, fall away from the state of grace?

True believers, by reason of the unchangeable love of God,342 and his decree and covenant to give them perseverance,343 their inseparable union with Christ,344 his continual intercession for them,345 and the Spirit and seed of God abiding in them,346 can neither totally nor finally fall away from the state of grace,347 but are kept by the power of God through faith unto salvation.348
