That He will perform His Word.
Psalm 145:14-16 (NKJ)
14 The LORD upholds all who fall,
And raises up all who are bowed down.
15 The eyes of all look expectantly to You,
And You give them their food in due season.
16 You open Your hand
And satisfy the desire of every living thing.
Romans 4:20-22 (NKJ)
20 He did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God, 21 and being fully convinced that what He had promised He was also able to perform. 22 And therefore it was accounted to him for righteousness.
