First gave their own selves to the Lord

1 Moreover, brethren, we do you to wit of the grace of God bestowed on the churches of Macedonia; 2 How that in a great trial of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality. 3 For to their power, I bear record, yea, and beyond their power they were willing of themselves; 4 Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints. 5 And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God. 6 Insomuch that we desired Titus, that as he had begun, so he would also finish in you the same grace also. 2 Corinthians 8:1-6
