1Cor 8:13 Wherefore, if meat make my brother to offend, I will eat no flesh while the world standeth, lest I make my brother to offend.
Paul, a very strong personality and the champion of Christian liberty was very careful to consider the convictions, yea, even the preferences of others.
Though he knew that liberty allowed him to follow the principles he was led to believe, he treasured Christian unity as a higher goal.
In Ephesians 4:3 he wrote, "Endeavouring to keep the unity of the Spirit in the bond of peace."
The word endeavor means to work at something, to strive for.
God would have us to set aside lesser concerns for the sake of unity in the church. I love the words of the Psalmist:
Psalms 133:1-3 A Song of degrees of David. Behold, how good and how pleasant it is for brethren to dwell together in unity! It is like the precious ointment upon the head, that ran down upon the beard, even Aaron's beard: that went down to the skirts of his garments; As the dew of Hermon, and as the dew that descended upon the mountains of Zion: for there the LORD commanded the blessing, even life for evermore.
