2 Corinthians 1:17
When we purpose things within ourselves it is "yes" or "no". But the purposes or promises of God are "yes"
We make up our minds according to the occasion and decide "yes" or "no" about something. It may be "yes" today but tomorrow the situation may change and it might be "no".
The promises of God are not made up to fit the situation but are decided beforehand. The situation agrees with what God has decreed, or it does not. For us as humans what is today "yes" may well be "no" tomorrow. We waffle and change our minds about the situation. We should make up our minds using God's everlasting principles as our base, and not with facts that change from day to day, or minute to minute.
For example, “Thou shalt not kill” never changes nor does the punishment for it, namely, the death of the killer. This applies to premeditated murder.
A man kills another man with a brick. Today we say he should be hanged: "yes". Tomorrow we look at his background: the brick thrower’s disadvantaged upbringing, he was beaten and abused all his life, he was half crazed with drugs; we reconsider and say he should not be hanged: "no". God's law does not change, period. If a man purposely sheds another man's blood, by the hand of other men must the killer’s blood be shed.
God allows leniency for situations such as accidents, self-defense and wartime battles. But he is not lenient about when the situation includes malice or forethought.
