Yes. The parable of the seed sower comes to mind. And this Scripture from our Lord:
John 10:27 "My sheep listen to My voice; I know them, and they follow Me. 28 I give them eternal life, and they will never perish. No one can snatch them out of My hand. 29 My Father who has given them to Me is greater than all. No one can snatch them out of My Father’s hand. 30 I and the Father are one.”
I think this verse speaks volumes concerning OSAS tropes from Rc's. He knows us, He gave us eternal life, we will never perish, no one can snatch us out of His hand. This is assurance for every true born-again follower of the Way.
May I add that when we truly follow Him He promises us we will suffer, we will be hated for His names sake. But, as you said, keep our eyes on Him, remembering His grace is enough.
