Sin contaminates, preventing a relationship with God. "Daniel resolved that he would not defile himself..." taking a deliberate stand against external sources of contamination (Dan 1:8). Godly values must rule all aspects of our lives, aware the evil within that comes out defiles us, with sexual sin being one of the most powerful (Mt 15:18). “If anyone defiles God’s temple, God will destroy him; for God’s temple is sacred, and you are that temple” (1 Cor 3:17, 6:18-20). Jesus said, not just wrong actions are sinful but so are wrong thoughts (Mt 5:27,28).
Regularly ‘spring-clean’ your life to replace the pollution with purity
personal responsibility, to actively “Put to death, whatever belongs to your earthly nature, sexual immorality, impurity…Cleanse and purify your hearts” (Col 3:5-10; Jas 4:8). Thank God for the blood of Christ for “If we confess our sin, He is faithful and just and will forgive us our sins and purify us from all unrighteousness” (1 Jn 1:9). We are not to continue in sin but walk in newness of life in Christ, not returning to that which once held us (Rom 6:1,4; Gal 5:1; 2 Pet 2:22).
