'Confidence' in the Bible

But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.

For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;

For indeed we have had the good news [of salvation] preached to us, just as the Israelites also [when the good news of the promised land came to them]; but the message they heard did not benefit them, because it was not united with faith [in God] by those who heard.

Therefore let us draw near with confidence to the throne of grace, so that we may receive mercy and find grace to help in time of need.

so that you will not be [spiritually] sluggish, but [will instead be] imitators of those who through faith [lean on God with absolute trust and confidence in Him and in His power] and by patient endurance [even when suffering] are [now] inheriting the promises.

Therefore, my brothers, since we have confidence to enter the sanctuary by the blood of Jesus,

let us approach [God] with a true and sincere heart in unqualified assurance of faith, having had our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.

Cast not away therefore your confidence, which hath great recompence of reward.

And faith is of things hoped for a confidence, of matters not seen a conviction,

By faith he kept the Passover and the sprinkling of the blood [on the doorposts], so that the destroyer of the firstborn would not touch them (the firstborn of Israel).

So we can say with confidence, "The Lord is my helper, and I will not be afraid. What can man do to me?"

Remember your leaders [for it was they] who brought you the word of God; and consider the result of their conduct [the outcome of their godly lives], and imitate their faith [their conviction that God exists and is the Creator and Ruler of all things, the Provider of eternal salvation through Christ, and imitate their reliance on God with absolute trust and confidence in His power, wisdom, and goodness].
