Jesus said:

I am the door, if any one enter in by me,

he shall be saved.

John 10:9

Strive with earnestness

to enter in through the narrow door.

Luke 13:24

For narrow the gate

and straitened  the way

that leads to life,

and they are few who find it. .

Matthew 7:14

 Ask, and it shall be given to you.

Seek, and you shall find.

Knock, and it shall be opened to you.

For every one that asks receives;

and he that seeks finds;

and to him that knocks it shall be opened.

Or what man is there of you who,

if his son shall ask of him a loaf of bread,

will give him a stone;

and if he ask a fish, will give him a serpent?

If therefore you, being wicked,

know how to give good gifts to your children, how much rather shall

your Father who is in the heavens

give good things

to them that ask of him?

Matthew 7:7-11

Not every one who says to me,

Lord, Lord,

shall enter into the kingdom of the heavens,

but he that does the will of

my Father who is in the heavens ...

Whoever therefore hears these my words

and does them, I will liken him to a prudent man, who built his house

upon the rock;

Matthew 7:21-24

Thou art the Christ,

the Son of the living God.

And Jesus said:..

on this rock

I will build my assembly,

Matthew 16:16-18

From the time that the master of the house

shall have risen up

and shall have shut the door,

and ye shall begin to stand without

and to knock at the door, saying:

Lord, open to us;

and he answering shall say to you,

I know you not whence ye are:

then shall you begin to say:

We have eaten in thy presence and drunk,

and thou hast taught in our streets;

and he shall say:

I tell you:

I do not know you whence you are;

depart from me, all you workers of iniquity.

Luke 13:25-27

 Unless ye are converted

and become as little children,

ye will not at all enter

into the kingdom of the heavens.

Matthew 18:3

Let the wicked forsake his way,

and the unrighteous man his thoughts;

and let him return unto Jehovah,

and he will have mercy upon him;

and to our God,

for he will abundantly pardon.

Isaiah 55:7

Draw near to God,

and he will draw near to you.

James 4:8

Jesus says to him,

I am the way, and the truth, and the life.

No one comes to the Father

unless by me.

John 14:6

  Having therefore, brethren, boldness

for entering into the holy of holies

by the blood of Jesus,

the new and living way

which he has dedicated for us

through the veil, that is, his flesh,

and having a great priest

over the house of God,

let us approach with a true heart,

in full assurance of faith...

Hebrews 10:19-22
