The Bible clearly teaches 2 types or stages of being victorious:

1.) Victorious over unbelief - instantaneous, when you first believe, unconditional, by faith.
...this is the victory having overcome the world: our faith. 1 John 5:4.

2.) Victorious over Satan, the flesh, worldliness - takes time, throughout your entire life, conditional, by works.

....I write to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one. 1 John 2:14.

Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Galatians 5:25.

Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. 1 John 2:15.
