whose tongue utters no slander, who does no wrong to a neighbor, and casts no slur on others; who despises a vile person but honors those who fear the LORD; who keeps an oath even when it hurts,
and does not change their mind;
Keeping an oath even when it hurts and not change your mind as the winds of uncertainty blow on you. This is righteous chararcter. We should not keep changing our minds. Sometimes living in the light and at other times basking in darkness. Sometimes obeying the sinful nature of the Devil in you and at other times claiming that you know God and His righteous ways. If you know, then why do you keep changing your minds, as the wind blows in your direction you sway to the right and left? Keep your oath even when it hurts. Do not change your mind. Keep walking the right path that leads to righteousness. The unsteady will fall and be destroyed along the way. A double minded man is always unsteady in all his ways. If you desired a righteous life at one time, why do you have to change your mind as the wind of influence beats on you vehemently? Stay firm and resist the Devil and he will flee from you forever. God's promise is there and He will fulfill it, if you obey Him fully.
But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. That person should not expect to receive anything from the Lord. Such a person is double-minded and unstable in all they do.
