They were bowmen and could shoot arrows and sling stones with either the right or the left hand; they were Benjaminites, Saul's kinsmen. (1Ch 12:2)
by truthful speech, and the power of God; with the weapons of righteousness for the right hand and for the left (2Co 6:7)
[I'm writing this post as a right-hander. If you are left-handed just reverse the illustration.]
We all have our strengths and weaknesses. The intense white light of Christ's glory cannot ever be fully reflected in any one man; instead it is spread, like in a prism into the multicoloured wisdom of God displayed in the Church. This is how God has ordained it to be, one body but may parts, each with our own unique strength arranged just as God has desired. So that together we represent the fullness of Christ.
Our right hands represent our strengths; they are used more and so have become stronger.
Our right hands represent our skills; the things which through a combination of practice, natural ability, and the Spirit's anointing we have become especially good at.
The right hand represents a place of honour. This is why Christ is seated at the right hand of God.
As members of the body, we all have our areas of strength, skill and recognition, but it is important that we realise we don't have to be limited just to those areas.
You don't need to be a healing ministry to lay hands on the sick and see them recover. You don't need to be a prophet to bring the word of the Lord. You don't need to be an evangelist to share the good news about Jesus with a friend or colleague. You just need to be willing.
Don't just expect that someone more qualified will come along. The right man for the job, is the man or woman of God who is in the right place at the right time. You may be the only representative of Christ that comes across that person or that need.
Don't let your strengths, your skills, or the gift that people recognise in you become a box that restricts you. God will use your right hand, but he will use your left hand also!
