'Assure' in the Bible

Then He said, “I assure you: You will see heaven opened and the angels of God ascending and descending on the Son of Man.”

Jesus replied, “I assure you: Unless someone is born again, he cannot see the kingdom of God.”

Jesus answered, “I assure you: Unless someone is born of water and the Spirit, he cannot enter the kingdom of God.

“I assure you: We speak what We know and We testify to what We have seen, but you do not accept Our testimony.

Then Jesus replied, “I assure you: The Son is not able to do anything on His own, but only what He sees the Father doing. For whatever the Father does, the Son also does these things in the same way.

“I assure you: Anyone who hears My word and believes Him who sent Me has eternal life and will not come under judgment but has passed from death to life.

“I assure you: An hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live.

Jesus answered, “I assure you: You are looking for Me, not because you saw the signs, but because you ate the loaves and were filled.

Jesus said to them, “I assure you: Moses didn’t give you the bread from heaven, but My Father gives you the real bread from heaven.

“I assure you: Anyone who believes has eternal life.

So Jesus said to them, “I assure you: Unless you eat the flesh of the Son of Man and drink His blood, you do not have life in yourselves.

Jesus responded, “I assure you: Everyone who commits sin is a slave of sin.

I assure you: If anyone keeps My word, he will never see death—ever!”

Jesus said to them, “I assure you: Before Abraham was, I am.”

“I assure you: Anyone who doesn’t enter the sheep pen by the door but climbs in some other way, is a thief and a robber.

So Jesus said again, “I assure you: I am the door of the sheep.

“I assure you: Unless a grain of wheat falls to the ground and dies, it remains by itself. But if it dies, it produces a large crop.

“I assure you: A slave is not greater than his master, and a messenger is not greater than the one who sent him.

I assure you: Whoever receives anyone I send receives Me, and the one who receives Me receives Him who sent Me.”

When Jesus had said this, He was troubled in His spirit and testified, “I assure you: One of you will betray Me!”

Jesus replied, “Will you lay down your life for Me? I assure you: A rooster will not crow until you have denied Me three times.

“I assure you: The one who believes in Me will also do the works that I do. And he will do even greater works than these, because I am going to the Father.

“I assure you: You will weep and wail, but the world will rejoice. You will become sorrowful, but your sorrow will turn to joy.

In that day you will not ask Me anything.“I assure you: Anything you ask the Father in My name, He will give you.

“I assure you: When you were young, you would tie your belt and walk wherever you wanted. But when you grow old, you will stretch out your hands and someone else will tie you and carry you where you don’t want to go.”
