Through prayer we communicate with God; we access His power; ours hearts are filling with joy and with His peace, that is beyond human understanding; we will be strengthening ourselves in the Lord and in His mighty power, as Paul advises us to do in Ephesians 6:10.
God tells us through the prophet Jeremiah, that He is the one who makes plans and carries them out, and we need to call on Him, if we want Him to respond. Would this be just a formally call? We all know that is not so.
God answers those who are sincere and seek him desiring to get an answered. His desire is to communicate with us, to strengthen our steps on the path of faith; He is revealing us things that we can't learn from someone else. Of course He wants us to have faith, to receive what He is revealing to us and act accordingly.
“Thus says the Lord who made it, the Lord who formed it to establish it (the Lord is His name): ‘Call to Me, and I will answer you, and show you great and mighty things, which you do not know.’"
Being "born again" of the incorruptible seed of the Holy Spirit, changes "our inner man." That is our spirit and this will transform it completely, as it will become one with the Spirit of God. But we will not be able to keep it "renewed" without a constant and devoted prayer life.
David shows us the solution for moments of despair, in Psalm 40. Many theologians say that this is a prophetic psalm of David, referring to Jesus in times of despair in the garden of Gethsemane. Whether this is about David, or it is prophetic, about Jesus Christ, the message is the same. In tough times, if the child of God, trusts totally in Lord God, his desperate cry for help, will receive an answer. Our Heavenly Father has all power in heaven and on earth and intervenes to save us, no matter how severe our situation is. You may say that Lord Jesus still had to go through the ordeal of arrest, mockery, scourging and crucifixion for the sins of whole humanity, even if He prayed. Is true, but Lord Jesus ended His prayer with:
"“Father,” he said, “if you will, take this cup of suffering away from me. Not my will, however, but your will be done.”” (Luke 22:42).
He knew that this was the purpose of His coming to earth, and that His Father heard His cry ("deesis" in the original Greek = prayer, supplication, need, demand) and gave him supreme power to go through the ordeal. God does that for all His children, never leave us alone and always choose the most beneficial for us, even though many times we think we had a better solution.
Jesus did not sin and never erred, it was perfect in his living, and still had a constant and dedicated life of prayer. He spent time daily, in the presence of the Father, and that refilled Him with the Holy Spirit. We need to pray with faith, to ask God's help in all aspects of our lives and seek to enter the presence of God on daily basis, way more than Jesus did. Only living filled with Holy Spirit and led by Him, we will see the promises of the Bible being fulfilled in our lives .
"I waited patiently for the Lord; And He inclined to me, And heard my cry. He also brought me up out of a horrible pit, Out of the miry clay, And set my feet upon a rock, And established my steps. He has put a new song in my mouth— Praise to our God; Many will see it and fear, And will trust in the Lord. Blessed is that man who makes the Lord his trust, And does not respect the proud, nor such as turn aside to lies.”
