You ask for many things, and rightly so, for prayer is the wing of the soul. Yet I see in your request a great thirst for signs and wonders, for the miraculous gifts of tongues and healings. Let me remind you of a greater marvel: that a sinner should speak the word of Christ with boldness, and that hearts of stone should be softened. Do you not know that John the Baptist worked no miracle, yet all Judea went out to him? His boldness, his holy life, these drew the multitudes. So also the apostles did not at first go forth with signs, but with the fire of the Spirit, and the place was shaken because they prayed for boldness to speak the word.
Do not set your heart too much upon the outward wonders, as if without them the gospel is weak. The gospel is the power of God, whether confirmed by signs or not. Signs are His to give as He wills; sometimes He bestows them even upon unworthy men, as Balaam, for the sake of others. But what profit was it to them? They perished all the more. Seek rather the gift of a right life, of love unfeigned, of humility. The poor man Peter, having no silver or gold, yet had authority to chastise Ananias. That authority came not from miracles but from the boldness of his manner of life. So you also, if you cast away all you possess, if you follow Christ, you may be as Peter. But if you cling to the world and ask for signs, you risk falling into the snare of pride. Did not the Corinthians, puffed up by their gifts, tear the church apart?
Pray then for the one thing needful: that God would open a door for the word, that He would grant you and your team boldness to speak the mystery of Christ as you ought. This is the true miracle, that a timid tongue should be set on fire, that bonds and fears should become the very things that make you speak the more. For can any man bind the tongue of an evangelist? The more he is bound, the more he runs. If the outreach should be canceled, do not be dismayed; God is not hindered. Paul in chains exhorted the Colossians to pray for his boldness, not for his release. He knew that his bonds made the word run swifter.
As for learning Spanish, whether by study or by gift, be zealous, but let it be for the edification of the hearers. If God gives the gift of tongues, remember He gives it as He wills, not as we demand. Yet if you never speak in other tongues, still let your life be a loud tongue, crying repentance. That is the marvel that silences the adversary, not the sight of a ghost lifted up, but a soul lifted from sin.
And for protection from wicked men and the evil one, indeed pray without ceasing. But know that the greatest protection is the peace of a good conscience and the covering of humility. If you suffer for the gospel, that is the gift of grace, a free gift making Christ your debtor. Rejoice in that, not in the exultation of powers. So go forth; make Christ known; trust the word to do its work. Whether signs follow or not, the word will not return empty. The power is in the Name, not in the vessel. Only be bold, be holy, and give thanks in all things.
