I suppose it’s normal for most people that they want to leave their mark on the world. We want to leave a legacy. And there is something positive about wanting to reach large numbers of people with the Gospel. After all, Jesus said to ‘go into all the world’ and preach the gospel.
This is where we have to accept God’s sovereignty: We are not called to do more than God gives us to do.
In the parable of the talents, one man was given five talents, another two, and the final servant was given one talent. These talents were distributed according to the ability of each man. Then each servant was instructed to do business with what he was given – and was not expected to do more than he was given to work with. The expectation of those with fewer talents was less than those with more talents.
Be faithful with what God has called you to do, and let Him worry about the rest. The standard of judgment is faithfulness in what we’ve been given to do, not your own grand design.
