Psalm 6 : Here David explains his condition to God and asks God to heal him. He then asks God to deliver him for His(God) sake because David understood very well that if he dies, he will not be able to praise thus he was pleading for more time to praise God for he still wanted to see God's works in and around his life, he still sought more time to know more of God therefore he asked God to deliver him. Now realise this, David doesn't cry before his enemies but cries before God pouring out his whole heart, and from that he gets strength to stand boldly before his enemies and casts hem away. He tells the enemies to depart from him not because God responded, but because God heard him : we are often worried about whether God will respond or not, but the biggest thing you need to grasp is that God heard you. For if God hears you the rest is up to Him and His own timing, be sure of the fact that He heard you. For if He heard you, why worry about how long He will take to respond for if He responds immediately its His will, and if He doesn't respond immediately it is still His will, just stick close by His will. Tell your enemies to back off, because God heard you and it is never in God's plan to cause you destruction, His plan for you is life, be sure that at the end - no matter when it is - you will have life, regardless of the current enemies and regardless of the current condition, because you cried to Him with an earnest heart. Now tell your enemies to RUN!!!! for God has heard your prayer and when He responds it won't well for them, tell them to go AWAY!!!! because your deliverance is surely coming. Don't let the enemy see your tears, show them your courage and faith in your Father, Jesus Christ and the Holy Spirit.Take heart and trust God's will and timing for these are always perfect, perfect for you and perfect for His purpose.
