The Bible tells us that each and every day God is telling us He exists as we look on what we can see of His world in His creation, for example the stars, and indeed these days, the cosmos. These all say “There is a God and He made us”. Great musicians have a style of composition unique to them, so those who know music recognise the composer of a classical piece without being told who it is. So it is with the created world.
But God in His foreordained plan also did something extremely dramatic which proves His existence. He took upon Himself a body, in the Person of Jesus Christ becoming a genuine human being, but without losing his divinity! Jesus Christ, came on a mission as Saviour and to this end, went to the cross at Calvary and there suffered and died as the Perfect sacrifice, satisfying God’s justice for the sins of all who believe and trust in Him. The Lord Jesus is the greatest proof to this world that God exists and through His gift we know that God “is” Love.
If we want to know more of what God is like and what He wants us to do then we can read the life of the Lord Jesus Christ in the Gospels (the New Testament). These says John, “Are written that you might believe that Jesus is the Christ, the Son of God, and that believing you may have life through his name.” I urge you all to prayerfully and humbly read these precious Gospels.
