Matthew 24:45 - "Who then is a faithful and wise servant, whom his lord has made ruler over his household?"
Who is faithful? The one who spends his time doing what God has called him to do. Or as Jesus put it, the one who takes up his cross and follows Him. The one who denies his fleshly desires and spends his life on the things God desires him to do.
God may be calling you to pray for the sick or to disciple a new Christian. But you're busy, so you glide on with good intentions and tell God you'll do it later. Well later is NOW. Decide today that you are going to be the faithful and wise servant. Serve His interests instead of your own.
Do you want Him to show Himself strong for you? Then take up Jesus' thoughts today. Discover and take up His purpose for your life. Now is the time to be faithful!
