Will the same grace that saved us also keep us saved even though we don't deserve it?
Yes. The same grace that made salvation possible will keep those who are His, even though no one deserves to stay saved. Believers remain saved because of God's unmerited favor, not personal merit, provided they have been truly saved in the first place.
Les explains that salvation begins by God's grace, not by human deserving. He asks whether a person deserved it, and the answer is no. He then argues that the same grace is going to keep those who are His, even though we don't deserve it. None of us deserve to stay saved, but we do because of His grace, if we have been truly saved in the first place. He also clarifies that grace is not license; it does not tell the believer to go out and do what they please. Yet when a believer, under the power of the Holy Spirit and trying to walk pleasing in God's sight, fails, God does not kick him out. Les uses the illustration of a parent watching a toddler take first faltering steps: when the child falls, the parent does not give him a boot but picks him up, gets him on those wobbly feet, and gets him going. That is what God does.
