'Assured' in the Bible

Now I want you to know, believers, that what has happened to me [this imprisonment that was meant to stop me] has actually served to advance [the spread of] the good news [regarding salvation].

for I know [with confidence] that this will turn out for my deliverance and spiritual well-being, through your prayers and the [superabundant] supply of the Spirit of Jesus Christ [which upholds me].

And the peace of God [that peace which reassures the heart, that peace] which transcends all understanding, [that peace which] stands guard over your hearts and your minds in Christ Jesus [is yours].
