God blessed Mr. Tom O’Connor with a tremendous family in both size and character! Praise God for his life and be cheerful that God has made him whole again.

“But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.” 1 Thessalonians 4:13-14
