Romans 11:22 See then the goodness and the severity of God: towards them indeed that are fallen, the severity; but towards thee, the goodness of God, if thou abide in goodness. Otherwise thou also shalt be cut off.
To be saved you must be in a state of Grace. To be in a state of Grace you must be free from sin. "All have sinned". You are not saved, you are redeemed, you salvation is dependent on your obedience to Christ and His will. To sin, and we all sin, you demonstrate will full disobedience to Christ by. Matthew 7:21 "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven."
And I think you have forgotten Paul
Philippians 2:12 "Wherefore, my dearly beloved, (as you have always obeyed, not as in my presence only but much more now in my absence) with fear and trembling work out your salvation"
You are not saved, you are redeemed.
