The problem with just stating that the bible commands that we are to care for the poor is that it is a cold hard law which will either make us fall into despair because there is always poor and we can’t help them all or we will be proud because we are doing more then the next Christian or church. Christians need to be motivated by grace first and foremost. As Jerry Bridges says “We are brought into God’s Kingdom by grace; we are sanctified by grace; we receive both temporal and spiritual blessings by grace; we are motivated to obedience by grace; we are called to serve and enabled to serve by grace; we receive strength to endure trials by grace; and finally, we are glorified by grace. The entire Christian life is lived under the reign of God’s grace.” So if this quote is true then the ministry of social Justice must be motivated by grace but how is this so?
The bible gives us a great example in 2 Corinthians 8, in verse 1-5 Paul tells us about the example of the Macedonians who out their poverty they want to give money and be abundantly generous. But Paul Gives us the theology that motivates their giving Paulstates “For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sakes he became poor, so that you through his poverty might become rich” (2 Corinthians 8:9). The motivation for their giving is the fact that Jesus gave up his riches and made us rich. Once you were poor, once you were spiritually destitute and Jesus left behind the riches of heaven and became so poor for you. It is in the cross we see the great exchange that Paul describes here in economic terms. Because of the cross we are able to give our money away because Jesus has given us the example of how to treat riches just as he gave his riches away, we, like the Macedonians, are free to give our money to help those who are poor. Therefore it is because God has been generous towards us in Jesus and the cross that we can be generous towards those who are needy and suffering in our world.
