You could not have inherited your faith through Baptism. It took faith to be baptized.
I'm not assured of maintaining faith until my dying breath, and thus I am not assured of salvation until I stand before Christ and hear my judgment.
I cannot maintain my faith. Our Lord Jesus promises to do it.
When we reject opportunities of grace, that gift of faith begins to shrink. If we're not careful (working out our salvation in fear and trembling) that faith could be gone without us even knowing it.
Nonsense. We are sealed with God's Holy Spirit which is our guarantee of our inheritance. It isn't anything that we do but it is everything that He has done. We do nothing but thank God for His grace.
He is our Great Shepherd who watches over us. NO ONE (not even us) will snatch us out of His hands to the praise of His glory.
No one save you.
Amen. In support I add the following: "When he had received the drink, Jesus said, 'It is finished.' With that, he bowed his head and gave up his spirit." (John 19:30). It is finished. The debt is paid in full with a receipt.
No one wants to answer the question: Why is St. Paul working out his salvation in fear and trembling?
No one guarantees our inheritance. Not even the Holy Spirit. To do so would be violation of our free will. If God wanted to violate our free will, He could have us all immaculately conceived, free of original sin.
It took faith to be baptized.
Yes. The faith of those around me. Just as the paralytic was healed of his sin not by his faith, but by the faith of those surrounding him.
I cannot maintain my faith.
Yes, you can. You don't get to sit on the couch of Life with a remote control when you "come to Jesus". Those who do not work, shall not eat.
There are no guarantees, but what you make of your faith. If you think you don't have the power to walk away from Christ, you are gravely mistaken.
