The problem is when one is told they are saved by believing something Jesus did to secure them so they can have heaven when they physically die. (But they may not be)
Instead of telling them to trust Jesus as who God through the prophets declared Him to be in order to be born from above; And then choose to follow Him.
One who was saved they knew it....they most likely came Alive at their new birth.....And honestly they can know when they are not walking in steps in light of the Faith of Jesus.
So if you really were saved why would you have to doubt? You knew it! And if ya want to continue to know you keep steps with the Spirit. It is knowledge that is the key. For eternal life is to know God and Jesus Christ who He sent.
3The gatekeeper opens the gate for him, and the sheep listen for his voice. He calls his own sheep by name and leads them out.
You see...so the problem is not telling the once saved they are lost when they know they are protected by their shepherd.
The problem is filtering scriptures through OSAS....and holding this doctrine of beliefs instead of Trusting Jesus Christ allowing the Spirit to lead one into all truth.
For no one can lay any foundation other than the one already laid, which is Jesus Christ.
It is Jesus that is the beginning and the end...not the scriptures filtered through Osas.
