1 Corinthians 15:2; Hebrews 3:6; Hebrews 3:14

and by which iyou are being saved, if you jhold fast to the word I preached to youkunless you believed in vain.

but Christ is faithful over God’s house as ya son. And zwe are his house, if indeed we ahold fast our confidence and our boasting in our hope.1

14 For we have come to share in Christ, hif indeed we hold our original confidence firm to the end.
