Dad needs to set an example of being a servant, as Jesus was, in everything from teaching, earning money and listening to doing the dirtiest household tasks. Jesus left us an example that we might follow in his steps. He stooped and washed feet, and we are called to live a life like his.
To profess to be a Christian without living it does more harm than good.
So let’s make life work a lot better for us: walk your talk, practice what you preach.
[Jesus said] "Not everyone who says to Me, `Lord, Lord,' will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter. (Matthew 7:21 NASB)
