By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, which you have heard is coming, and now it is already in the world.
We have come to know and have believed the love which God has for us. God is love, and the one who remains in love remains in God, and God remains in him.
If someone says, “I love God,” and yet he hates his brother or sister, he is a liar; for the one who does not love his brother and sister whom he has seen, cannot love God, whom he has not seen.
And we know that the Son of God has come, and has given us understanding so that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
And not only this, but we also celebrate in our tribulations, knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope.
After you have suffered for a little while, the God of all grace, who called you to His eternal glory in Christ, will Himself perfect, confirm, strengthen, and establish you.
