In a construction of a house, the groundwork is very important. Likewise, in a Christian life, it is very important to lay a foundation, which refers to casting away sins. The Bible, which is a record of God¡¯s Word, says that if we repent of sins and believe the Lord Jesus, we can be saved, and it tells us to live a holy life according to the Word of God. It means we have to throw away sins. A Christian life itself is the process of casting away sins and resembling God.
