We can't claim that we aren't talented in praying and then neglect it. We can't claim to not be compassionate and therefore avoid the messiness of other people's lives. Professing that we don't have the gift of generosity is a weak excuse not to tithe. God tells us in 2 Timothy 3:16-17 that His Word is powerful enough to equip us for every good work. There are no aspects of the Christian life that God isn't able to help us be prepared for. We get to operate within our strengths, but there are good works that God is calling all of His people to engage in. These are the things that set us apart and define our allegiance. When He is preparing us through His Word to accomplish them, we really don't have an excuse not to follow through.
