I was shown that love of the world has to a great extent shut Jesus from the church. God calls for a change, a surrender of all to Him. Unless the mind is educated to dwell upon religious themes, it will be weak and feeble in this direction. But while dwelling upon worldly enterprises, it will be strong; for in this direction it has been cultivated, and has strengthened with exercise. The reason it is so difficult for men and women to live religious lives is because they do not exercise the mind unto godliness. It is trained to run in an opposite direction. Unless the mind is constantly exercised in obtaining spiritual knowledge and in seeking to understand the mystery of godliness, it is incapable of appreciating eternal things because it has no experience in that direction. This is the reason why nearly all consider it uphill business to serve the Lord.
When the heart is divided, dwelling principally upon things of the world, and but little upon the things of God, there can be no special increase of spiritual strength. Worldly enterprises claim the larger share of the mind, calling into exercise its powers; therefore in this direction there is strength and power to claim more and more of the interest and affections, while less and less is reserved to devote to God. It is impossible for the soul to flourish while prayer is not a special exercise of the mind. Family or public prayer alone is not sufficient. Secret prayer is very important; in solitude the soul is laid bare to the inspecting eye of God, and every motive is scrutinized. Secret prayer! How precious! The soul communing with God! Secret prayer is to be heard only by the prayer-hearing God. No curious ear is to receive the burden of such petitions. In secret prayer the soul is free from surrounding influences, free from excitement. Calmly, yet fervently, will it reach out after God. Secret prayer is frequently perverted, and its sweet designs lost, by loud vocal prayer. Instead of the calm, quiet trust and faith in God, the soul drawn out in low, humble tones, the voice is raised to a loud pitch, and excitement is encouraged, and secret prayer loses its softening, sacred influence. There is a storm of feeling, a storm of words, making it impossible to discern the still, small voice that speaks to the soul while engaged in its secret, true, heartfelt devotion. Secret prayer, properly carried out, is productive of great good. But prayer which is made public to the entire family and neighborhood is not secret prayer, even though thought to be, and divine strength is not received from it. Sweet and abiding will be the influence emanating from Him who seeth in secret, whose ear is open to answer the prayer arising from the heart. By calm, simple faith the soul holds communion with God and gathers to itself divine rays of light to strengthen and sustain it to endure the conflicts of Satan. God is our tower of strength.
