If you have no works your faith is dead and you may as well not have any faith because you aren’t saved. To think you will get over with claiming you have faith and then do nothing as a confirming result you are decieving yourself.
What types of works save us? All kinds actually because many things we do can prove we truly believe.
1815 The gift of faith remains in one who has not sinned against it. But “faith apart from works is dead”: when it is deprived of hope and love, faith does not fully unite the believer to Christ and does not make him a living member of his Body.
2447 The works of mercy are charitable actions by which we come to the aid of our neighbor in his spiritual and bodily necessities. Instructing, advising, consoling, comforting are spiritual works of mercy, as are forgiving and bearing wrongs patiently. The corporal works of mercy consist especially in feeding the hungry, sheltering the homeless, clothing the naked, visiting the sick and imprisoned, and burying the dead. Among all these, giving alms to the poor is one of the chief witnesses to fraternal charity: it is also a work of justice pleasing to God:
He who has two coats, let him share with him who has none and he who has food must do likewise. But give for alms those things which are within; and behold, everything is clean for you. If a brother or sister is ill-clad and in lack of daily food, and one of you says to them, “Go in peace, be warmed and filled,” without giving them the things needed for the body, what does it profit?
1430 Jesus’ call to conversion and penance, like that of the prophets before him, does not aim first at outward works, “sackcloth and ashes,” fasting and mortification, but at the conversion of the heart, interior conversion. Without this, such penances remain sterile and false; however, interior conversion urges expression in visible signs, gestures and works of penance.
