We cannot "encourage ourselves in the Lord our God" unless we are in fellowship with Him. Hope springs from oneness with God. Faith springs from oneness with God. If you are having trouble "whipping up faith," perhaps a moment of self-examination will be valuable. Can you "commune with your own heart upon your bed, and be still"? In that moment between you and your pillow, is there any shadow of a disobedience which robs you of sleep?"Stand in awe, and sin not: commune with your own heart upon your bed, and be still" ~ Psalm 4:4
Can you face what you see in your own heart, knowing God sees it too? Can you face it and sleep? "Hope springs eternal" from the heart that is one with God. But if there is one single point on which we are not obeying His slightest whisper, we cannot "commune with our own hearts ... and be still."
Most particularly we will not "be still." We cannot.
If something is blocking our oneness with Christ, we are noisy with excuses and alibis and explanations and dodges. And sometimes we are noisy with service! If something is there between you and Christ, you know it. So does He. And "if our heart condemn us, God is greater than our heart, and knoweth all things." We do not need to go on with troubled hearts. With guilty consciences. God is greater than your guilty conscience. He poured out His own blood on Calvary to free you from sin and the guilt that follows it. Give it to Him.e is "greater than our heart." Norman Grubb suggests keeping "short accounts with God." If we do, hope will be a part of our daily peace. If there is "nothing between" we are confident of all things in God.
"... Commune with your own heart ... and be still. ... If our heart condemn us not, then have we confidence toward God."
