A mark sets apart, it identifies or makes a difference in man or things. In times past, and even now among some tribes, marks are incised on peculiar parts of the body to identify persons as part of the tribe. The mark enables them to be identified for favour during festivities, preserved or attacked during battle.
Every individual carries a mark and this mark attracts certain persons, favours, opportunities, threats or even destruction to them. The mark explains why some persons usually have a toll of events in their lives. Life responds to the mark you carry.
In Ezekiel 9:3-6, God had to put mark on the foreheads of those who grieve and lament over all the detestable things that was done in Jerusalem at the time and those without the mark were destroyed. God took His covenant with Abraham seriously when Abraham obeyed and carried the mark of circumcision despite his old age as seen in Genesis 17: 9-11, 23-24.
As Christians, the covenant relationship between us and God must have a mark. The covenant isn’t about age, but doing what is God-like and making everything around you resemble God by the mark. This mark is Holiness, Hebrew 12:14.
Repent and denounce every other mark you carry and make a decision to live a life of holiness in every aspect on a daily basis, Galatians 6:17.
Remain marked for God.
