1 Corinthians 1:9; 1 Corinthians 4:17; 1 Corinthians 10:13

9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.
17 For this cause have I sent unto you Timotheus, who is my beloved son, and faithful in the Lord, who shall bring you into remembrance of my ways which be in Christ, as I teach every where in every church.
13 There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able ; but will with the temptation also make a way to escape, that ye may be able to bear it.
