Look at the contrast in the readings today. "So shall my word be that goes forth from my mouth; It shall not return to me void, but shall do my will, achieving the end for which I sent it." (Is 55:10-11) The power of God's Word makes fertile and bears fruit.
"In praying, do not babble like the pagans, who think that they will be heard because of their many words." (Mt 6:7-15) Our words have such little affect.
Jesus teaches us how to pray. He gives us the words we are to pray, the Our Father. These words are given to us from God the Father. This is how He wants us to pray to Him. These words are His words thus they make our lives fertile and we begin to bear fruit. Fruit produced by doing the Father's Will. Fertility cultivated by the Holy Spirit. Our hearts tended by Christ Jesus, our Merciful Savior.
We can babble and babble seeking our own will, expressing our own understanding, and living according to our selfish desires, but our hearts and our lives will be barren. Eventually we will cease to tend them and instead seek only to quench them. In seeking to quench our barren souls, all manner of sin and distraction will be presented to us until we find one to our liking. Once found we will cling to it as if it were our very life. But it is not, it is a lie. In living according to our own will, we live a lie. In the desert while the plants seem to be dead the roots are still lush and green. A drop of water and the plants spring to life. If we do not seek to do the Father's Will, we have no roots. The drop of water is easily wasted. Our thirst will never be satisfied. We often blame God saying that He does not answer our prayers. The truth is much harsher. We do not want to do His Will. His response is unimportant if it is not in line with our desire, our want, or our will. Lent is a time to repent, to turn away from our selfishness, and believe in the Good News. Seriously taking time to pray and Meditate on the Our Father is a good place to start. In doing so we can put down roots. Rooted in doing the Father's Will, in imitation of Christ, we can follow the promptings of the Holy Spirit into the desert. There we will find strength to overcome our temptations, and comfort in the Loving Mercy of the Most Holy Trinity.
