When we seem to doubt God's love and distrust His promises we dishonor Him and grieve His Holy Spirit. How would a mother feel if her children were constantly complaining of her, just as though she did not mean them well, when her whole life's effort had been to forward their interests and to give them comfort? Suppose they should doubt her love; it would break her heart. How would any parent feel to be thus treated by his children? And how can our heavenly Father regard us when we distrust His love, which has led Him to give His only-begotten Son that we might have life? The apostle writes, "He that spared not His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?" Romans 8:32. And yet how many, by their actions, if not in word, are saying, "The Lord does not mean this for me. Perhaps He loves others, but He does not love me."
All this is harming your own soul; for every word of doubt you utter is inviting Satan's temptations; it is strengthening in you the tendency to doubt, and it is grieving from you the ministering angels. When Satan tempts you, breathe not a word of doubt or darkness. If you choose to open the door to his suggestions, your mind will be filled with distrust and rebellious questioning. If you talk out your feelings, every doubt you express not only reacts upon yourself, but it is a seed that will germinate and bear fruit in the life of others, and it may be impossible to counteract the influence of your words. You yourself may be able to recover from the season of temptation and from the snare of Satan, but others who have been swayed by your influence may not be able to escape from the unbelief you have suggested. How important that we speak only those things that will give spiritual strength and life!
Angels are listening to hear what kind of report you are bearing to the world about your heavenly Master. Let your conversation be of Him who liveth to make intercession for you before the Father. When you take the hand of a friend, let praise to God be on your lips and in your heart. This will attract his thoughts to Jesus.
All have trials; griefs hard to bear, temptations hard to resist. Do not tell your troubles to your fellow mortals, but carry everything to God in prayer. Make it a rule never to utter one word of doubt or discouragement. You can do much to brighten the life of others and strengthen their efforts, by words of hope and holy cheer. STC 119,120
I can do all things through Christ[a] who strengthens me. Philippians 4:13 (New King James Version)
