On one occasion the disciples of Jesus were discussing among themselves who was the greatest in the kingdom of Israel. Man tends to bask in his own self-importance, doesn't he? This tends to produce arrogance and a false sense of self-righteousness. Jesus set a child in the midst of his disciples and said, "Unless you turn and become like children you will never enter the kingdom of heaven. Whoever humbles himself like this child is the greatest in the kingdom of heaven" (Matt. 18:3-4).
Humility is not the only admirable trait children possess that needs to be emulated. There are many others. Particularly, there is the innocence of a child. There is nothing pretentious about children. They are as pure as the newly fallen snow. It is refreshing to be in their presence and to be surrounded by such innocence. It makes you feel purer yourself. Unfortunately, if we live long enough, we lose that purity and innocence because we become guilty of sin (Rom. 3:10, 23). However, we can become pure again by obeying the gospel and having our sins washed away (Acts 22:16). In so doing, we become pure and innocent in the eyes of God as if we had never committed one act of sin.
Having once been cleansed, we are to remain "…blameless and innocent, children of God without blemish in the midst of a crooked and twisted generation, among whom you shine as lights in the world" (Phil. 2:15). This is not to suggest that we are capable of living above sin once we become Christians, but our purity and innocence before God is maintained as long as "we walk in the light…" (1 Jn. 1:7). The reason for this is because the blood of Jesus keeps us clean (1 Jn. 1:7).
We ought to thank God every day for the marvelous gift of his Son (2 Cor. 9:15). In him we have victory and cleansing!
