What is the will of God after the Cross?
23 And this is his commandment, that we believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. 24 Whoever keeps his commandments abides in God, and God in him. And by this we know that he abides in us, by the Spirit whom he has given us. (from 1 John 3)
16 Rejoice always, 17 pray continually,18 give thanks in all circumstances; for this is God’s will for you in Christ Jesus. (from 2 Thes. 5)
15 For it is God’s will that by doing good you should silence the ignorant talk of foolish people. (from 1 Pet. 2)
I urge, then, first of all, that petitions, prayers, intercession and thanksgiving be made for all people— 2 for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness. 3 This is good, and pleasesGod our Savior, 4 who wants all people to be saved and to come to a knowledge of the truth. (from 1 Tim. 2)
40" For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.” (from Jn. 6)
