You have nothing to apologize for. Do you know that in pre WW2 Germany much of the Chruch supported Hitler. He stood for righteousness in a corrupt society, he said all the right things and won the nations heart. All the while he was a wolf in sheeps clothing and it was only after he got the power he sought that people noticed his fangs.
In truth if we stay close to our Lord we will hear His voice and not follow another (red emphasis mine):
Joh 10:27 My sheep hear My voice, and I know them, and they follow Me.
Joh 10:1 Truly, truly, I say to you, He who does not enter into the sheepfold by the door, but going up by another way, that one is a thief and a robber.
Joh 10:2 But he who enters in by the door is the shepherd of the sheep.
Joh 10:3 The doorkeeper opens to him, and the sheep hear his voice, and he calls his own sheep by name and leads them out.
Joh 10:4 And when he puts forth his own sheep, he goes before them, and the sheep follow him. For they know his voice.
Joh 10:5 And they will not follow a stranger, but will flee from him, for they do not know the voice of strangers.
Joh 10:6 Jesus spoke this parable to them, but they did not understand what it was which He spoke to them.
Joh 10:7 Then Jesus said to them again, Truly, truly, I say to you, I am the door of the sheep.
Joh 10:8 All who came before Me are thieves and robbers, but the sheep did not hear them.
Joh 10:9 I am the door. If anyone enters in by Me, he shall be saved and shall go in and out and find pasture.
Joh 10:10 The thief does not come except to steal and to kill and to destroy. I have come so that they might have life, and that they might have it more abundantly.
Joh 10:11 I am the Good Shepherd. The Good Shepherd lays down His life for the sheep.
Joh 10:12 But he who is a hireling and not the shepherd, who does not own the sheep, sees the wolf coming and leaves the sheep and runs away. And the wolf catches them and scatters the sheep.
Joh 10:13 The hireling flees, because he is a hireling and does not care for the sheep.
Joh 10:14 I am the Good Shepherd, and I know those that are Mine, and I am known by those who are Mine.
Our calling is to stay close to theMasters heart and listen to His voice There is no fear in that and He has promised us this-
Joh 10:28 And I give to them eternal life, and they shall never ever perish, and not anyone shall pluck them out of My hand.
Joh 10:29 My Father who gave them to me is greater than all, and no one is able to pluck them out of My Father's hand.
