There is only one verse with Grace and joy/rejoice in it.
Barnabas, who after having come and seeing the Grace of God, rejoiced. And he exhorted all with purpose of heart to abide near the Lord. Acts 11:23

God’s Grace produces joy and rejoicing!
Joy is a fruit of the spirit! Galatians 5:22

“Ones joy is directly proportional to the Grace he has received, more Grace means more joy. The more aware one is and understands what God by his Grace has done/is doing, the more real joy he will have and the more he will be able to rejoice!”

Here is what I found looking at the joy scriptures;
There are two kinds of joy, the first leads to appropriate actions, (Matthew 13:44, and again, the kingdom of heaven is compared to a treasure being hidden in a field, which finding, a man hid; and for the joy of it, he goes and sells all things, as many as he has and buys that field.) the other joy seems to be just emotional and when tests/trials come, the person gives up, as shown in Matthew 13:20+21; and the seed sown on the rocky places is this; the one hearing the word and immediately receiving it with joy, but has no root in himself, but is temporary, and tribulation or persecution occurring because of the word, he is at once stumbled. So we see, where one has faith, joy is real, brings real responses and where the word meets not faith, joy is at best temporal and not lasting and any test, the person gives up.

Jesus said in John 15:11, I have spoken these things to you that my joy may abide in you and your joy may be made full.
And Jesus also said in Matthew 25:21 and his Lord said to him, well done good and faithful servant. You were faithful over a few things; I will set you over many. Enter into the joy of your Lord.
