David was careful to lead a blameless life, which stems from a blameless heart. To have a blameless heart, David has to see no evil, do no evil, and be away from people who do evil, or practice deceit and speak falsely. David agrees to the fact that sin is indeed powerful and can cause us to sin if we are not careful.
Today God has given us the Holy Spirit so that we can live our lives guided by the Holy Spirit. Let us learn to depend on the Holy Spirit to give us the desires to do what is good (Eph 5:17). Jesus has given us a new heart and a new Spirit so that we can be victorious over sin by following the Spirit’s leading in our lives (Eph 5:25).
