Matthew 5:21-37
In His sermon on the mount, Jesus had been bringing distinction between the teachings of the religious leaders of the day and what God truly expected from His followers. The religious leaders were teaching a works based righteousness that encouraged people to find value in their outward efforts; however, Jesus taught them that having a pure heart would lead to right actions. The heart and actions cannot be separated.
To bring clarity to this issue, Jesus illustrated the importance of having a pure heart AND proper actions. Jesus makes the connection between the heart and actions by looking at a couple issues: murder/hatred (5:21-26), adultery/lust (5:27-30), divorce (5:31-32), and making promises (5:33-37). The religious leaders viewed murder as sin (5:21), but Jesus took this issue one step further by exposing hatred as the heart condition which leads a person to murder (5:22). Many people were taking pride in the fact that they had never murdered someone, but hatred or unjustified anger toward another is an internal sin which has the potential to lead to an external, sinful action. Jesus challenged His followers to confess any areas of anger or hatred before coming to worship God (5:23-26).
Many of the religious leaders thought highly of themselves because they had never committed adultery (5:27), but Jesus equated lust (an internal sin) with adultery, which is the outward manifestation of lust (5:28). The only way to combat outward sin is by changing the heart (5:29-30). Jesus also examined another issue being abused by the religious leaders – divorce (5:31-32). They taught that divorce could take place when a husband felt it was necessary or when a major offense took place; however, Jesus reminded them that a marriage could only be dissolved when sexual immorality has occurred. Marriage is a serious commitment made before God and should not be taken lightly. Jesus also exposes the religious leaders’ soft view of making promises in the name of God (5:33-37). When they could not fulfill a promise or an oath, they would justify it. Again, this was an issue of the heart. Jesus wanted His followers to keep their promises, especially if they had used His name to guarantee it.
Guarding our heart is imperative in our relationship with God, but if we focus all our attention on the external, we will not see long-term victory. The writer of Proverbs says it like this, “Keep your heart with all diligence, for out of it spring the issues of life” (Proverbs 4:23). What a person believes in their heart will eventually be revealed in their actions.
Dear God, I give You control of my heart.
