We all know and very often hear from various preachers, that those who are led by the Spirit, are the children of God. That is taken from Romans 8:14.
But we can not just take one verse from the Bible, out of context, and make a doctrine of it.
Yes, God guides his children by his Holy Spirit, but in Romans 8:13, 14, it very clearly talks about the Holy Spirit helping us in our struggle against sin. That is what those two verses of chapter 8:13, 14 are about.
It is not saying anything about making decisions, or being guided by the Holy Spirit, when making a decision.
Yes, we can be guided by the Holy Spirit when making decisions, but these two verses here, are not talking about that.
