Just to get started here, let me give you the definition I came up with for a Timothy Mom:
A Timothy Mom is a mother who, like Eunice and Lois, makes it her aim to not only teach her children the scriptures, but also models a life of genuine faith in Christ to them whether her husband does or not. A Timothy Mom labors in prayer, in talking, in listening, in rebuking, in correcting, in coaching, in encouraging, in nurturing, in serving and in modeling faith in Christ for the prize of seeing Christ formed in her own children.
Bless the Lord, O my soul; And all that is within me, bless His holy name! Bless
the Lord, O my soul, And forget not all His benefits: Who forgives all your iniquities, Who heals all your diseases, Who redeems your life from destruction, Who crowns you with lovingkindness and tender mercies, Who satisfies your mouth with good things, So that your youth is renewed like the eagle's. - Psalm 103:1-5
"Behold, the LORD'S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear..." Isaiah 59:1
