Jesus said, "I have come that you may have life, and have it to the full." If we die and return to the earth, and that is the end, there is a certain vanity to life. It creates a very selfish attitude, "I better get all I can while I'm here." If you believe in Christ, and eternity, then life takes on a whole new and much richer meaning. As Jesus says, and as we are discovering, it's life to the full.
When your heart overflows with love, there comes a great desire to love and serve others. Jesus said that out of our innermost being would flow rivers of living water. It a glorious thing to be touched by Jesus love, and a glorious thing to share the overflow of that love with others.
The best way to lead is by example. Lead in a way that your family will follow. Lead in a way that your workmates will respect you for your attitude and integrity. Lead in a way that you live without regrets. When you lead, others will follow.
