Whether we are caring for our elderly parent, making widgets at the factory, or driving the church van, or spending quality time with our children, we are to do it heartily as we would for the Lord Himself.
Having a "kingdom mindset" will greatly help us in being faithful from day to day. A person with the kingdom mindset sees themselves as God's servant and is aware that they are under his authority at all times. Jesus illustrated the kingdom mindset in the parable of the talents (Matthew 25:14-30). In the parable, the master entrusted his money to his three servants prior to a journey. Upon return, he rewarded the two servants who had invested the money. He rebuked the third who had not invested, gave his portion to the most profitable servant, and had him punished severely.
The kingdom mindset recognizes that we will give an account to God, just as the servants gave account to the master. God entrusts many such resources to us and expects us to put them to use for his interests. At the end of the age, we'll have to give an account to God for how we lived and what we did with what he gave us. Paul wrote:
"Therefore we make it our aim, whether present or absent, to be well pleasing to Him. For we must all appear before the judgment seat of Christ, that each one may receive the things done in the body, according to what he has done, whether good or bad." 2 Corinthians 5:9-10 NKJV
Make each day count for Him in everything you do. You only go through life once, so do it right the first time...
