Sure it is. Works/good fruit/overcoming sin flow from grace for believers- and those works are optional nonetheless. They flow from the love pored into our hearts by the Holy Spirit (Rom 5:5), to put it another way. And this makes perfect sins of such verses, again, as:
"If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned." John 15:5-6
"If you want to enter life, keep the commandments.” Matt 19:17
"To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life." Rom 2:7
"When you were slaves to sin, you were free from the control of righteousness. What benefit did you reap at that time from the things you are now ashamed of? Those things result in death! But now that you have been set free from sin and have become slaves of God, the benefit you reap leads to holiness, and the result is eternal life." Rom 6:20-22
"Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord." Heb 12:14
"Therefore, brothers and sisters, we have an obligation—but it is not to the flesh, to live according to it. For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live. For those who are led by the Spirit of God are the children of God." Rom 8:12-14
"Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life. " Gal 6:7-8
So that's what it means to 'work out your salvation', or 'make you calling and election sure'.
