But while the distinction between the life we naturally seek and that to which God calls us is felt by all from age to age, the forms in which this distinction makes itself felt vary as the world grows older. To all men living in a world of sense it is difficult to live by faith in the unseen. To every man it is the ultimate, severest test of character to determine for what ends he will live and to carry out this determination; but the temptations which avail to draw men aside from their reasonable decision are various as the men themselves. Paul names the temptations to which the Corinthians, in common with the Israelites, were exposed: idolatry, fornication, murmuring, tempting Christ. He saw clearly how difficult it was for the Corinthians to discard all heathen customs, how much of what had been brightest in their life they must sacrifice if they were to renounce absolutely the religion of their parents and friends and all the joyous, if licentious, customs associated with that religion. Apparently some of them thought they might pass from the Christian communion to the heathen temple, and after partaking of Christ's sacrament eat and drink in the idolatrous festival, entering into the entire service. They seemed to think that they might be both Christians and pagans.
Against this vain attempt to combine the incompatible Paul warns them. Do not tempt Christ, he says, by experimenting how far He will bear with your conformity to idolatry. Some of the Israelites did so, and were destroyed by serpents. Do not murmur that you are hereby severed from all the enjoyments of life, dissociated from your heathen friends, blackballed in society and in business, excluded from all national festivals and from many private entertainments; do not count up your losses, but your gains. Your temptations are severe, but "there hath no temptation taken you but such as is common to man." Every man must make up his mind to a certain kind of life and go through with it. No man can unite in his own life all advantages. He must deliberate and choose; and having made his choice, he must not lament what he loses or be tempted from striving to gain what he judges best by weakly and greedily craving for the second-best also. He may win the first prize; he may win the second: he cannot win both, and if he tries, he will win neither.
The practical outcome of all that Paul has thus rapidly passed in review he utters in the haunting words, "Let him that thinketh he standeth take heed lest he fall." In this life we are never beyond the reach of temptation. And these temptations to which all of us are exposed are real; they do sufficiently test character and show what it actually is. Our suppositions regarding ourselves are often untrue. There is no reality corresponding. Our state is actually not such as we conceive it to be. We are at ease and complacent when we ought not to be at ease. We think we stand secure when we are on the point of falling. We live as if we had reached the goal when the whole journey is yet before us. Our future may be very different from what we wish or expect. Mere satisfaction with our present condition is a very insecure foundation on which to build our hope for the future. Mere reliance on a profession we have made, or on the fact that we are within reach of means of grace, tends only to slacken our energies. Heedlessness, taking things for granted, failure to sift matters thoroughly out, an indolent unwillingness to probe our spiritual condition to the quick--this is what has betrayed multitudes of Christians. "Wherefore let him that thinketh he standeth take heed lest he fall."
If determined wickedness has slain its thousands, heedlessness has slain its tens of thousands. Through lack of watchfulness men fall into sin which entangles them for life and thwarts their best purposes. Through want of watchfulness men go on in sin which exceedingly provokes God, till at last His hand falls heavily upon them. Every man is apt to lay too much stress on the circumstance that he has joined himself to the number of those who own the leadership of Christ. The question remains, How far has he gone with his Leader? Many an Israelite compassionated the poor heathen whom he left behind in the land of Egypt, and yet found that, with all his own apparent nearness to God, his heart was heathen still. Whoever takes it for granted that things are well with him, whoever "thinketh he standeth"--he is the man who has especial and urgent need to "take heed lest he fall."
