The answer is no we won't because we won't want to sin/won't be capable.
The problem with that flow chart shows a fundamental, but incredibly common misunderstanding of the Christian idea of salvation, that it is simply a one time event instead of a process. Before I get into the details of that, let's start at the beginning: In the beginning God the universe, the Earth, and eventually mankind. Mankind chose to sin and separated himself from God. God then instituted the Covenant, the law, and then Christ. The sacrifice of Christ, as he was a perfect man, and God himself taking on the punishment of our sins, it was sufficient for mankind to be redeemed to God, if man chooses to accept. Once you accept Christ as your Lord and Savior, you are "saved" and become a new creation in Christ. However, these new creations are improved over even over the unfallen man of Adam (which only had the breath of life) as the spirit of God himself, the Holy Spirit literally dwells inside of them. Now, because we are still living in this fallen world and have our fallen human nature, we are going to sin, but once Christ comes back and restores creation so that Heaven and Earth become one, sin and evil will be no more, we won't be able to sin, nor really want to sin because we will have reached our perfection within Christ.
