Your question presupposed that salvation is acted out by the believer. Coming at it from a reformed/calvanistic point of view here is out I would answer it.
Salvation starts by God in eternity past through his election. Here is how Wayne Grudem describe election in is book Systematic Theology chapter 32. (Sorry could not get a direct link to the page)
Then if God calls those who will be save, then the believer receive the gift of salvation. In God eye, the believer is already in heaven. Then salvation is an act of God, and also God is the one responsible for the calling and the keeping on the path of faith.
Here is how Romans present this thought:
For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified. (Romans 8.29-30) ESV
God chooses, the christian respond in faith and God keeps the believer during all the life of the believer. Salvation is then a state matter.
Although the end matter as well, a Christian is called to perseverance in his faith. If he was to fall he would be sinning, not loosing is salvation. Because God choosed the believer before any good work or any faith on his part. The sinning does not rob salvation, but his joy , his peace and different gifts.
In 1 Jonh one of the test of a true christian is his walk in the light.
If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. (1 john 1.6-7) ESV
In a way salvation is a path, but not unto salvation but unto holiness.
