Romans 4:19-20 KJV

19 And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah's womb:
20 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;

2 Corinthians 4:17-18 KJV

17 For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory;
18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.

Philemon 1:6 KJV

6 That the communication of thy faith may become effectual by the acknowledging of every good thing which is in you in Christ Jesus.
