There is nothing impossible for God for Him everything is possible because He is the author and creator of the entire universe is the owner of life and of everything created like heaven, earth, stars, the moon, the sun .. .the whole universe was constituted by Him and nothing that was constituted was without Him.
Our faith brings us closer to God since we believe that by it we understand that God created the universe.
Hebrews 11: 3
"By faith we understand that the universe was prepared by the word of God, so that what is seen was not made of visible things."
(The American Standard Bible).
Our God has promised wonderful things for those who believe him and if He said it I believe it. He has promised faithfulness and mercy for all nations even in our infidelities.
Ezekiel 17:24
24 And all the trees in the field will know that I, Jehovah, have cut down the sublime tree, raised up the low tree, dried the green tree, and made the dry tree green. I the Lord have said it, and I will do it.
Reina-Valera 1960 (RVR1960).
For example in this verse we can look at God's mercy and faithfulness to the nations, here the trees symbolically represent the nations and although each one suffers the consequences of their own sins He refers to the mercy poured out on the deserts specifically on the tree dry when the prophet describes that He will make him green again and that is our hope because our God will green all the nations that cry out to Him from their hearts to heal our land since He is the only one who can with His divine and transforming power heal and restore the dead socially and spiritually.
If God said it, I believe it. How will I know if He said it? for the scriptures are evidence of his power, fidelity and love and everything prophesied everything absolutely everything has been fulfilled.
Furthermore, the word of God is just, fair and truthful and each one of them has been fulfilled through the ages.
Psalms 33: 4-5
4 For upright is the word of the Lord,
And all his work is done with fidelity.
5 He loves justice and judgment;
The earth is full of Jehovah's mercy.
King James Version (RVR1960)
