'Freely' in the Bible

Being justified freely by his grace through the redemption that is in Christ Jesus:

But praise be to God that though you were the servants of sin, you have now given yourselves freely to that form of teaching under which you were placed;

For the reward of sin is death; but what God freely gives is eternal life in Jesus Christ our Lord.

He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely 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.

He who has the power of comforting, let him do so; he who gives, let him give freely; he who has the power of ruling, let him do it with a serious mind; he who has mercy on others, let it be with joy.
