Without grace, you can't give wholeheartedly. 

The New Testament believers gave freely because great grace was upon them all. (Acts 4:31>)

Zacchaeus gave freely because he met Jesus, full of grace. Meeting Jesus impacted him profoundly, and he repaid money fourfold. 

The eunuch gave his life to God soon as He learned about Jesus. He immediately took water baptism after Philip preached the gospel. 

A lady used expensive perfume on Jesus. To some, it felt like a waste. But her abundant gratitude and gift are a memorial for us. 

Aquila and Priscilla had a tent business but made time to help the apostles and teach Apollos the right doctrine.

John received great revelation after Jesus took a special interest in him when young. John stayed faithful till the appointed time to write the book of Revelation. 

Dear believer, stick with Jesus. He is full of grace and truth. You will become a completely new person and give cheerfully for the glory of God.

Maranatha, Praise God, and Amen.
