Sorry to hear of your grandmother's condition.
May God comfort you and your family.
As to scripture, I like the following ...1 Corinthians 13:1 If I speak in the tongues of mortals and of angels, but do not have love, I am a noisy gong or a clanging cymbal.God Bless ...
2 And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but do not have love, I am nothing.
3 If I give away all my possessions, and if I hand over my body so that I may boast, but do not have love, I gain nothing.
4 Love is patient; love is kind; love is not envious or boastful or arrogant
5 or rude. It does not insist on its own way; it is not irritable or resentful;
6 it does not rejoice in wrongdoing, but rejoices in the truth.
7 It bears all things, believes all things, hopes all things, endures all things.
8 Love never ends. But as for prophecies, they will come to an end; as for tongues, they will cease; as for knowledge, it will come to an end.
9 For we know only in part, and we prophesy only in part;
10 but when the complete comes, the partial will come to an end.
11 When I was a child, I spoke like a child, I thought like a child, I reasoned like a child; when I became an adult, I put an end to childish ways.
12 For now we see in a mirror, dimly, but then we will see face to face. Now I know only in part; then I will know fully, even as I have been fully known.
13 And now faith, hope, and love abide, these three; and the greatest of these is love.
Now is probably a bad time to point out that this verse contradicts any notion of "faith alone." :-)
