Our Lord’s exhortation in these verses is to be generous in our behaviour to all men. In the spiritual life beware of walking according to natural affinities. Everyone has natural affinities; some people we like and others we do not like. We must never let those likes and dislikes rule in our Christian life. "If we walk in the light as God is in the light," God will give us communion with people for whom we have no natural affinity.
It is true that Jesus Christ is with us in our temptations, but are we going with Him in His temptations? Many of us cease to go with Jesus from the moment we have an experience of what He can do. Watch when God shifts your circumstances, and see whether you are going with Jesus, or siding with the world, the flesh and the devil. We wear His badge, but are we going with Him? "From that time many of His disciples went back and walked no more with Him."
Until we are born again, the only kind of temptation we understand is that mentioned by St. James – "Every man is tempted, when he is drawn away of his own lust, and enticed." But by regeneration we are lifted into another realm where there are other temptations to face, viz., the kind of temptations Our Lord faced. The temptations of Jesus do not appeal to us, they have no home at all in our human nature. Our Lord’s temptations and ours move in different spheres until we are born again and become His brethren. The temptations of Jesus are not those of a man, but the temptations of God as Man. By regeneration the Son of God is formed in us, and in our physical life He has the same setting that He had on earth. Satan does not tempt us to do wrong things; he tempts us in order to make us lose what God has put into us by regeneration, viz., the possibility of being of value to God. He does not come on the line of tempting us to sin, but on the line of shifting the point of view, and only the Spirit of God can detect this as a temptation of the devil.
The word "temptation" has come down in the world; we are apt to use it wrongly. Temptation is not sin, it is the thing we are bound to meet if we are men. Not to be tempted would be to be beneath contempt. Many of us, however, suffer from temptations from which we have no business to suffer, simply because we have refused to let God lift us to a higher plane where we would face temptations of another order.
The main idea in the region of religion is – Your eyes upon God, not on men. Do not have as your motive the desire to be known as a praying man. Get an inner chamber in which to pray where no one knows you are praying, shut the door and talk to God in secret. Have no other motive than to know your Father in heaven. It is impossible to conduct your life as a disciple without definite times of secret prayer.
