The love God wants

"He said to him the third time, 'Simon, son of Jonah, do you love Me?' Peter was grieved because He said to him the third time, 'do you love Me?'And he said to Him, 'Lord, You know all things; You know that I love You.'Jesus said to him, 'Feed My sheep.'" John 21.17

Why did Jesus ask Peter if he loved Him? From my understanding, he wanted to teach about pure and true love. Just as faith requires attitude, love also requires action. Those who think that pure love is a feeling are completely wrong. It is not. Just as  and faith, it also requires sacrifices.

Holy Spirit's grief

"And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice." Ephesians 4.30-31

No member of a body is capable of hurting the other. Rather, the members of a body cooperate with each other harmoniously to please the head. So must be the Church of the Lord Jesus. All that comprise it must work together for the edification of the Church, whose Head is Jesus. If there is a strange body among the members, there will be conflict with others. Sooner or later, the foreign element will be expelled.

ANGER

"Be angry, and do not sin; do not let the sun go down on your wrath, nor give place to the devil."       Ephesians 6.26-27

The world we live in does not allow us to be perfect. There are moments where we get angry. However, we cannot allow this anger to turn into grief. Before the sun goes down that anger must give way to repentance and forgiveness. 
By doing this, the devil will not find any gaps to enter into your life.
