As believers we are to follow Christ's example of being willing to meet people where they are. Fully God, yet he humbled himself and stepped into humanity on our behalf. He gave up the glory of heaven to come and redeem mankind, born in the most humble way. He did not consider his royal position ahead of our need for him; he humbled himself and became obedient to death in order that we might experience firsthand the love of God.
In the same way, we are to have the mindset of Christ concerning those around us. We are to consider them above ourselves. Paul has given us plenty of instruction in Romans 12 on how to live in harmony with one another. In today's passage he reminds us that we should rejoice with those who rejoice and morn with those who mourn. This can only happen when we genuinely love and care for each other. By showing interest and concern for others above our own need, we become invested in their lives. Doing so brings us to the point of being able to share with them in every circumstance. Rejoicing and mourning with them is a natural response to the love shared, this is why Paul started out by saying "love must be sincere" ( Romans 12:9 ).
To live in harmony with each other we have to be willing to associate with everyone. As believers, we should not be conceited or overestimate ourselves. We should not be exclusive or snobbish toward one another and we should always be willing to include and care for those around us. Jesus told the disciples "If anyone wants to be first, he must be the very last, and the servant of all" ( Mark 9:35 ). This is the secret to getting ahead in life, putting others ahead of yourself and serving each other just as if you were serving the Lord. Jesus then took a child in his arms and went on to explain to them, "Whoever welcomes one of these little children in my name welcomes me; and whoever welcomes me does not welcome me but the one who sent me." ( Mark 9:37 ). Keeping this eternal perspective in mind will enable us to live in harmony with each other, rejoicing, mourning and caring for each other's needs just as if the Lord standing before us.
Today it is my prayer that you understand this wonderful truth and apply it to your life. May God bless you as you seek him and may he bring people into your path to be a blessing to, amen.
