"God CANNOT Lie"
17 Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. 18 God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope set before us may be greatly encouraged. ...
So you know by what this verse is saying, that God cannot lie, and everything He says in the bible is the truth. That can bring encouragement to anyone.
Numbers 23:19 (NIV)
19 God is not human, that he should lie,
not a human being, that he should change his mind.
Does he speak and then not act?
Does he promise and not fulfill?
When you pray and ask God for something, doesn’t he always answer yes, no, and not now. There is a reason why he has to say no, and not now, cause its not your time to have what you want. But God always provides for His Children.
1 John 1:10 (NIV)
10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
God cannot lie, so why would we lie about sinning. We want His word to always be in us.
Titus 1:1-2 (NIV)
1 Paul, a servant of God and an apostle of Jesus Christ to further the faith of God’s elect and their knowledge of the truth that leads to godliness— 2 in the hope of eternal life, which God, who does not lie, promised before the beginning of time.
An like Paul, we are servant’s of God, spreading the knowledge of Jesus Christ. We want people to know there is eternal life after death. All they have to do is believe and except Our Lord Jesus Christ as Our Savior.
