「且滿心確信，神所應許的，祂也必能作成。」－羅馬書4:21
對於神的應許，他不起絲毫疑惑，他堅立不搖地站在神所賜豐厚的祝福上。他沒有因信心軟弱而垂頭喪志，他的信心是越挫越勇的信心。
對亞伯拉罕來說，環境若是加倍的艱難，他相信神也要加倍的在他身上得著榮耀。
他「滿心確信，神所應許的，祂也必能作成。」在希臘原文中，神不僅「能」，祂更是「豐豐富富的能」；祂有充盈有餘的權能，祂也能充盈有餘的成就。
神的能力是無止無盡的，祂真正的限制是在於我們。
無論我們所求、所想、所禱告的，對祂來說都太微不足道了；我們期待的太少了。
神不斷的試著要擴大我們的眼界，讓我們有更大的仰望，更大的求告。但是我們常常太小覷了神。
祂的名是榮耀的「伊勒沙代」（希伯來文 El Shaddai，參創世記17:1），就是全豐全足的供應者，因此我們可以無限量的向祂求取，無止盡的向祂仰望。祂賜祝福的唯一條件就是照著「那運行在我們裡面的大能」。－宣信
"And being absolutely certain that whatever promise He is bound by, He is able to make good" (Rom. 4:20).We are told that Abraham could look at his own body and consider it as good as dead without being discouraged, because he was not looking at himself but at the Almighty One.
He did not stagger at the promise, but stood straight up unbending beneath his mighty load of blessing; and instead of growing weak he waxed strong in the faith, grew more robust, the more difficulties became apparent, glorifying God through His very sufficiency and being "fully persuaded" as the Greek expresses it. "that he who had promised was," not merely able, but as it literally means "abundantly able," munificently able, able with an infinite surplus of resources, infinitely able "to perform."
He is the God of boundless resources. The only limit is in us. Our asking, our thinking, our praying are too small; our expectations are too limited. He is trying to lift us up to a higher conception, and lure us on to a mightier expectation and appropriation. Oh, shall we put Him in derision? There is no limit to what we may ask and expect of our glorious El-Shaddai; and there is but one measure here given for His blessing, and that is "according to the power that worketh in us." --A. B. Simpson
