9460. 'From everyone whose heart is willing' means that all things should be offered out of love, and so in freedom. This is clear from the meaning of 'whose heart is willing' as in freedom. The reason why offering them out of love is meant is that all freedom is rooted in love; for what a person does out of love he does in freedom.

'Heart' has to do with love because it has to do with the will, see 7542, 8910, 9050, 9113, 9300.

All freedom is rooted in love or affection, 2870-2893, 3158, 9096, and this is why all worship must be offered in freedom, 1947, 2880, 2881, 7349.

2875. Goodness of life, or the affection for good, is instilled by the Lord by means of an internal way, without the person being at all aware of it, whereas the truth of doctrine, or faith, is instilled by an external way and introduced into the memory. From there it is called forth by the Lord in His own time and according to His own order and is joined to the affection for good. This happens in that person's freedom, for a person's freedom, as has been stated, flows from his affection. This is how faith is implanted and takes root. Whatever is done in freedom is joined to him, but that which is done under compulsion is not. This may become clear from the fact that nothing can possibly be joined to a person unless he has an affection for it. Affection is that which actually receives, and anything received that is contrary to his affection is contrary to his life. From this it is evident that the truth of doctrine, or faith, is incapable of being received except by the affection for it. But as is the affection so is the reception. It is the affection for truth and good, this alone, that receives the truth of faith, for they accord with each other, and because they accord they join themselves together.
