Couldn't God preserve us through the use of infinity? Can a lie become the truth?

Most importantly Jesus clearly stated over and over again that salvation comes only through faith in Him as your Saviour and Lord. He taught only 2 paths in life: 1 leads to destruction and the other leads to life. He was purposely being exclusive in all of His teachings, which is easily determined from a thorough reading of the NT. A lie is a lie and the truth is the truth. One can not be the other for they contradict each other.
