There are two kinds of habits, bad habits and good habits.
From the spiritual point of view, bad habits don't lead us to the Kingdom of Heaven, while good habits enable us to go to the heavenly country.
In order to enter the Kingdom of Heaven safely, we should have good habits.

John 3:3
In reply, Jesus declared, "I tell you the truth, no one can see the kingdom of God unless he is born again."

According to the teaching of Jesus, those who are reborn are able to go to the Kingdom of God. Being born again includes abandoning bad habits that deprive us of the opportunity to enter the Kingdom of Heaven, and keeping practicing good habits.

In the history of Israelites who walked the desert for 40 years, the results of Israelites complaining in every circumstance were destruction.
Having habits like disobedience, Saul, the first king of Israel, faced his miserable future.

1 Samuel 15: 22-23
But Samuel replied: "Does the LORD delight in burnt offerings and sacrifices as much as in obeying the voice of the LORD ? To obey is better than sacrifice, and to heed is better than the fat of rams.
For rebellion is like the sin of divination, and arrogance like the evil of idolatry. Because you have rejected the word of the LORD, he has rejected you as king."

On the other hand, the Bible recorded those who have good habits before God in Revelation.

Revelation 14:4 These are those who did not defile themselves with women, for they kept themselves pure. They follow the Lamb wherever he goes. They were purchased from among men and offered as firstfruits to God and the Lamb.

As the Bible says, we should be like those who have good habits by following God wherever He goes. Let us all be the children of God the Father and God the Mother, who get rid of all the wrong habits, and be clothed again with the habits of the heavenly people!
