There are so many examples given in scripture of those who without a doubt relied completely on God such as Jonah when in the belly of a great fish knew God was his only hope! ( Jonah 2 ).

We can put our trust in man with dyer consequences or we can put our trust in the Lord who is the only true help for us in this life! ( Jeremiah 17:5-10 ). 5 Thus saith the LORD; Cursed [be] the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD. 6 For he shall be like the heath in the desert, and shall not see when good cometh; but shall inhabit the parched places in the wilderness, [in] a salt land and not inhabited. 7 Blessed [is] the man that trusteth in the LORD, and whose hope the LORD is. 8 For he shall be as a tree planted by the waters, and [that] spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit. 9 The heart [is] deceitful above all [things], and desperately wicked: who can know it? 10 I the LORD search the heart, [I] try the reins, even to give every man according to his ways, [and] according to the fruit of his doings.

The following words from Psalm 62 says it all! ( Psalm 62:5-8 ). 5 My soul, wait thou only upon God; for my expectation [is] from him. 6 He only [is] my rock and my salvation: [he is] my defence; I shall not be moved. 7 In God [is] my salvation and my glory: the rock of my strength, [and] my refuge, [is] in God. 8 Trust in him at all times; [ye] people, pour out your heart before him: God is a refuge for us. Selah.
