Pride and lustful desires will lead you into temptation.

The devil can also set traps for you to fall into temptation.

But, God will not allow you to be tempted above what you can tolerate.

Instead,  He will make a way of escape for you.

One of the most important provision is through prayer. Therefore,

Watch (rise) and pray, lest you enter into temptation. The spirit indeed is willing, but the flesh is weak.” (Matthew 26:42)

No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it. (1 Corinthians 10:13) 

Then the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment. (2 Peter 2:9)
