That point will often be raised, for doubt is a seed which is sure to grow in lazy men's minds. I do not remember reading in Mr. Wesley's diary a question about his own salvation. He was so busy in the harvest of the Master that it did not occur to him to distrust his God. Some Christians have little faith in consequence of their having never sown the grain of mustard-seed which they have received. If you do not sow your faith by using it, how can it grow? When a man lives by faith in Christ Jesus, and his faith exercises itself actively in the service of his Lord, it takes root, grows upward, and become strong, till it chokes his doubts. Some have sadly morbid forebodings; they are discontented, fretful, selfish, murmuring, and all because they are idle. These are the weeds that grow in sluggards' gardens. I have known the slothful become so peevish that nothing could please them; the most earnest Christian could not do right for them; the most loving Christians could not be affectionate enough; the most active church could not be energetic enough; they detected all sorts of wrong where God himself saw much of the fruit of his Spirit. This censoriousness, this contention, this perpetual complaining is one of the nettles that are quite sure to grow in men's gardens when they fold their arms in sinful ease. If your heart does not yield fruit to God it will certainly bring forth that which is mischievous in itself, painful to you, and injurious to your fellow-men. Often the thorns choke the good seed; but it is a very blessed thing when the good seed comes up so thick and fast that it chokes the thorns. God enables certain Christians to become so fruitful in Christ that their graces and works stand thick together, and when Satan throws in the tares they cannot grow because there is no room for them. The Holy Spirit by his power makes evil to become weak in the heart, so that it no longer keeps the upper hand. If you are slothful, friend, look over the field of your heart, and weep at the sight.
