'Unbelief' in the Bible

And He did not do many miracles there [in Nazareth] because of their unbelief.

He wondered at their unbelief.And He was going around in the villages teaching.

Later, Jesus appeared to the eleven [disciples] themselves as they were reclining at the table; and He called them to account for their unbelief and hardness of heart, because they had not believed those who had seen Him after He had risen [from death].

Then He said to Thomas, “Reach here with your finger, and see My hands; and put out your hand and place it in My side. Do not be unbelieving, but [stop doubting and] believe.”

But he did not doubt or waver in unbelief concerning the promise of God, but he grew strong and empowered by faith, giving glory to God,

That is true. They were broken off because of their unbelief, but you stand by your faith [as believers understanding the truth of Christ’s deity]. Do not be conceited, but [rather stand in great awe of God and] fear [Him];

for if God did not spare the natural branches [because of unbelief], He will not spare you either.

And even they [the unbelieving Jews], if they do not continue in their unbelief, will be grafted in; for God has the power to graft them in again.

even though I was formerly a blasphemer [of our Lord] and a persecutor [of His church] and a shameful and outrageous and violent aggressor [toward believers]. Yet I was shown mercy because I acted out of ignorance in unbelief.

So we see that they were not able to enter [into His rest—the promised land] because of unbelief and an unwillingness to trust in God.

Let us therefore make every effort to enter that rest [of God, to know and experience it for ourselves], so that no one will fall by following the same example of disobedience [as those who died in the wilderness].

By faith [with confidence in God and His word] Noah, being warned by God about events not yet seen, in reverence prepared an ark for the salvation of his family. By this [act of obedience] he condemned the world and became an heir of the righteousness which comes by faith.
