The Holiness of God as Our Assurance that He Will Fulfill His Promises

A neighbor preparing for his birthday banquet comes to you and says: "May I borrow your large cooking pot? I will return it tomorrow after the banquet." After a dozen tomorrows, he still keeps your large cooking pot.

Men are unholy. They don't honor their word. They place little value on integrity. But God is not like unholy men. He is absolutely holy. Thus, when God promises something, he will surely fulfill it. In Psalm 89:35, he says: 

 "Once for all, I have sworn by my holiness--

and I will not lie to David--"

Such is the character of God. You cannot find any hint of falsehood in him.

You know that he promised that he will never leave you or forsake you (Heb. 13:5). Because he is holy, we have the assurance that in the most difficult circumstances, he is with those whom he has redeemed. "Is he a million miles away?" No! He is a God so near.

You know that he has promised that whoever hears his word and believes will no longer face judgment (John 5:24). Because he is holy, he will fulfill it. You don't have to worry about paying for your own sins. No condemnation awaits you for you are in him.

He promised that all things work together for the good of those who love God and are called according to his purpose (Romans 8:28). Because he is holy, he will fulfill it. You don't have to be anxious about that present trouble ruining you. It will only be for your welfare to bring you closer to God.

Numbers 23:19---"God is not a man, that he should lie,
    nor a son of man, that he should change his mind.
  Does he speak and then not act?    Does he promise and not fulfill?" (NIV)
