We must love the Lord with all our heart, first of all thank Him for His wonderful love for us, thank Him in an immense way, because as His word says, that He loved us since before the foundation of the world.
This is an infinite love, a totally great love, so much that He was given for us, for that we must give thanks and recognize His glory and His power forever.
In the first epistle of John we are told of this great love that God has for each of us:
19 We love him, because he first loved us.
20 If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?
21 And this commandment have we from him, That he who loveth God love his brother also.
1 John 4:19-21
This is a wonder of God for each one of us, as we read these words we notice the importance of loving, because if we do not love our brothers, we are not showing that we love God.
And God loved us first, isn’t that a good reason to love Him? And as we said before, we must demonstrate this love by loving our brothers, because if we hate our brothers, then the Father’s love is not in us.
So, let us love our brothers, just as the Father shows us that great love and in this way we can say that the Father’s love is in us.
