Pure
In nature, it is hard to find an element that is 100 percent free of flaws or contamination. Even gold has to be refined, separating the valued substance from its contaminates and impurities, giving it a higher quality, rarity and delicacy. Apply this concept to God's desire for us to lead pure lives by cultivating pure minds and bodies and by abstaining from thoughts of rebellion, lust and other wrongs. Purity shows the state of our hearts. Allowing impurities to continue in our lives makes us as useless to God as unrefined gold is to a jeweler. When we put our lifestyles, old habits and other desires ahead of serving God, we demonstrate  our lack of commitment to him.

There is a process of purity that leads to cleansed hearts and minds. It starts with faith in Jesus Christ, which then leads to confessing our sins and drawing near to God. With confession comes a spiritual transformation of our character, which demonstrates our commitment. With the power of Jesus' blood our sin-stained hearts can become white as snow. Through this purifying process, we become more valuable to God's work.

The pure in heart will see God.
