God is absolutely trustworthy

“God is not a man, so he does not lie. He is not human, so he does not change his mind. Has he ever spoken and failed to act? Has he ever promised and not carried it through?"  (Num. 23:19 NLT)

The unchangeable character of His purpose

“For when God made a promise to Abraham, since he had no one greater by whom to swear, he swore by himself, saying, “Surely I will bless you and multiply you.”And thus Abraham, having patiently waited, obtained the promise. For people swear by something greater than themselves, and in all their disputes an oath is final for confirmation. So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath, so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us.” (Heb. 6:13-18 ESV)

A trustworthy statement

“It is a trustworthy statement deserving full acceptance. For it is for this we labor and strive, because we have fixed our hope on the living God, who is the Savior of all men, especially of believers.” (2 Tim. 4:9-10 NASB)

When your heart trusts in Him, you are helped

“Blessed be the Lord, Because He has heard the voice of my supplication. The Lord is my strength and my shield; My heart trusts in Him, and I am helped; Therefore my heart exults, And with my song I shall thank Him” (Psalm 28:6-7, NASB).
