I will guard my ways.Psalm 39:1
Fellow-pilgrim, do not say in your heart, "I will go here and there, and I will not sin," for you are never so out of danger of sinning as to boast of security. The road is very muddy; it will be hard to pick your path so as not to soil your garments. This is a dirty world, and you will need to stay alert if you are to keep your hands clean. There is a robber at every turn of the road to rob you of your jewels; there is a temptation in every mercy; there is a snare in every joy; and if you ever reach heaven, it will be a miracle of divine grace to be ascribed entirely to your Father's power.
Be on your guard. When a man carries fireworks in his hand, he should be careful that he does not go near a candle; and you too must take care that you do not succumb to temptation. Even your everyday activities are sharp-edged tools; you must mind how you handle them.
There is nothing in this world to foster a Christian's piety, but everything to destroy it. How concerned you should be to look up to God, that He may keep you! Your prayer should be, "Hold me up, and I shall be safe." Having prayed, you must also watch, guarding every thought, word, and action, with holy jealousy. Do not expose yourselves unnecessarily; but if called to exposure, if you are called to go where the darts are flying, never venture forth without your shield; for if once the devil finds you without your armor, he will rejoice that his hour of triumph is come and will soon make you fall down wounded by his arrows. Although you cannot be killed, you may be wounded.
Be sober-minded; be watchful--danger may befall you at a time when everything seems to be secure. Therefore, pay attention, stay alert, watch and pray. No man ever fell into error through being too watchful. May the Holy Spirit guide us in all our ways, so they shall always please the Lord.
