I know the secret of the Christian life is following Jesus and He was a man who prayed all night, or early in the morning or stayed up well into the night spending time with His Father. It is where the Holy Spirit is drawing me to and has for some time. Intercessory prayer is for the strong and not for the weak.
Most of the time we still look to God as our last chance of the day giving Him our list of troubles and calling on Him to respond. Doubts creep in when we leave everything to Him at the last-minute.
At least we are standing our ground when we call for help and we do not lose hope or fall away. These are times when we actually might see daybreak from our knees being in prayer. For these are the nights that we feel the only friend we have left is Darkness.
