I have come to realize that God's Love for us knows no bound and He first demonstrated this when He sent His Son to die for the sins of the whole world, even if most people do not yet seem to realize this. God does not love us because we are perfect, nor for our good works, nor because we prayed yesterday, He loves us because He has chosen to (Matt 11:27)..... Oh, what a great privilege!
Therefore, when you make a mistake and the devil wants to hold you down with guilt, just tell him.... hello, God loves me! and go to God and make amends immediately. 2 Cor 12:9 explains this further, Christ is willing to help you through your weaknesses. The fact that He loved you while you were deep in sin is enough to tell you that a little fall would not make Him love you any less, so don't allow any devil to deceive you (Is 1:18).
Many Christians suffer down-time because they do not understand the magnitude of God's Love for them. Something goes wrong and God is blamed, lacking something and God is blamed once again. Blaming God does not solve problems, confessing His Love for you does a lot because it increases your confidence in Him. Many are poor not because they are lazy, but because they do not know their right in Christ for all-round prosperity (1Tim 5:18, 3Jn 1:2).
Come into the light of The Father's Love today! Allow the Holy Spirit to reveal more of the Father's Love to you (Rom 5:5), because only a Spirit can comprehend a Spirit. The Father's Love is sooooo..... great, our normal minds cannot comprehend it (Eph 3:18). And according to your understanding of this great Love, will you enjoy God on this earth (Eph 3:19), because God would not give you more than you can contain (Eph 3:20), He deals in sizes.
You cannot command more than what you know. Comprehending more of God's Love gives you power over the evil forces in this world. Remember all those cartoons, where good always win evil? Love would always prevail all.
