The second passage to which I desire to direct your attention you will find in the epistle to the Philippians, the fourth chapter, and in the sixth and seventh verses, “Be careful for nothing; but in everything by prayer and supplication, with thanksgiving, let your requests be made known unto God. And the peace of God, which passeth understanding, shall keep your hearts and minds through Christ Jesus.”
“Be careful for nothing.” This by no means signifies that we may be careless, thoughtless, or unconcerned about everything. That is not the meaning of it. The meaning is, not to be anxious about anything. This is one of the privileges of the children of God, that they are permitted, and not only permitted but invited, and not only invited, but commanded, to bring all their cares, sorrows, trials, and wants to their heavenly Father. To roll all their burdens upon God; to cast all their cares upon Him.
And because they are permitted, yea, commanded so to do, they have no need to be anxious about anything. However many or varied our difficulties or necessities, we should commit them all in believing prayer to God; but we should not be anxious. And why not? Because it is impossible to be anxious without dishonouring God.
If the men of the world see that we Christians are anxious, like themselves, they will have ground for saying, that our profession of having an Almighty Friend and Helper in heaven is only is profession; and, therefore, we dishonour God by not trusting in Him in the hour of need.
