'Freely' in the Bible

and are being justified [declared free of the guilt of sin, made acceptable to God, and granted eternal life] as a gift by His [precious, undeserved] grace, through the redemption [the payment for our sin] which is [provided] in Christ Jesus,

He who did not spare [even] His own Son, but gave Him up for us all, how will He not also, along with Him, graciously give us all things?

For with the heart a person believes [in Christ as Savior] resulting in his justification [that is, being made righteous—being freed of the guilt of sin and made acceptable to God]; and with the mouth he acknowledges and confesses [his faith openly], resulting in and confirming [his] salvation.
