We can conquer it, but only through the grace of God. However, that doesn’t mean we will never come to a point in our lives when we cannot/will not be tempted. The temptations merely change as we do. Considering we live in a sin-soaked world, we can’t avoid it, but we can overcome sins, one by one, day by day, which what Jesus meant by “give us this day our daily bread” and “lead us not into temptation” in the great prayer he taught us. Day by day God gives us the grace to live in holiness and to be perfected in his love. As long as we will to cooperate with his grace, we can and will overcome sin.
