Romans 12:7

or ministry, let us give ourselves to our ministry; or he that teacheth, to his teaching;

'ministry' -this word covers. lot of different jobs. 'Of service in general, including all forms of christian ministration tending to the good of the christian body.' (Vincent p. 157) 'General word for Christian service of all kinds' (Robertson p. 404)

Preaching is 'ministry' (Acts 6:4), but so is caring for the physical needs of another (Acts 6:1; 1 Timothy 5:10), assisting the congregation in some manner (Romans 16:1; Acts 12:25; 1 Corinthians 16:15), being. Deacon (1 Timothy 3:8). Any area of service in the body of Christ, is 'ministry'.

'let us give ourselves to our ministry' -'If your gift is that of serving others, serve them well' (Tay). 'The imperative phrase: "in that ministry!" throws this field wide open and bids the Romans plunge in.' (Lenski p. 763)

Point to Note:

Sometimes Christians think, 'Well, I've been doing this for awhile, maybe. should stand aside and let someone else do it'. Paul says, 'What are you good at? Well, then keep on doing it!' In fact, Paul would often tell people, to 'abound more and more' (1 Thessalonians 4:10)

The Apostles refused to get involved in something that would subtract from their time to teach others. Someone else could do that. But they couldn't leave the area of service that they were better qualified for, then anyone else. (Acts 6:2)

'or he that teacheth' -'aimed at the understanding' (Vincent p. 157) 'Teaching is instructing, making things plain' (Lenski p. 763). 'To give the sense so that they understood the reading' (Nehemiah 8:8). Are you able to make the hard-simple, the difficult-understandable? Then that is exactly what you need to be doing!
