Romans 9:1 says Paul knew he was on the right track because his conscience was prompted by the Holy Spirit. You know you can plan your actions all day long, but if the Spirit of God does not bear witness with you, it will not be God's best. The mind does help the spirit at times, but your best results will be when your mind and your spirit are working together. However the promptings of the spirit should always be honored above the mind.
If you know in your spirit that something is wrong, you should not allow reasoning to talk you into doing it. On the other hand, don't allow your reasoning to talk you out of doing something right! Let the Holy Spirit bear witness with you whether something is right or wrong. Allow your conscience to always be enlightened or prompted by the Holy Spirit.
"My conscience (enlightened and prompted) by the Holy Spirit always bearing witness with me..." Romans 9:1
