Rom 12:3 . . I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
"soberly" is from the Greek word sophroneo (so-fron-eh'-o) which means to be of sound mind, i.e. sane.
A popular saying going around is this: "You can be anything". No, you can't be anything, and it's unreasonable to think otherwise. Know your limits and stay within them; don't be setting impossible goals for yourself; especially in matters of faith and practice.
"Just as each of us has one body with many members, and these members do not all have the same function, so in Christ we who are many form one body, and each member belongs to all the others. We have different gifts, according to the grace given us.
. . . If a man's gift is prophesying, let him use it in proportion to his faith. If it is serving, let him serve; if it is teaching, let him teach; if it is encouraging, let him encourage; if it is contributing to the needs of others, let him give generously; if it is leadership, let him govern diligently; if it is showing mercy, let him do it cheerfully." (Rom 12:4-8)
Some church managers have a really bad habit of recruiting people to teach Sunday school who don't have a gift for it in accordance with Rom 12:3-8, 1Cor 12:1-30, and Eph 4:7-12. Well; if teaching is not your spiritual specialty; then the sensible thing to do is turn them down. Stay within your limits like Rom 12:3 says, and don't let those managers pressure you into submission by making you feel guilty for refusing. Nobody gains points with Christ by going off-reservation.
